In this paper, we propose a simple construction of CCCs of length Nn (n e N) based on paraunitary matrices of size N × N. This algorithm can generate CCCs from N-shift cross-orthogonal sequence sets for n > 1. Then, we introduce an easy implementation of the proposed algorithm by multiplexers and read-only memories (ROMs), i.e., a multiplier-free implementation. As multipliers are avoided, substantial reduction of construction complexity for CCCs is obtained as compared to the existing works.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122916586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The H-NTF can be derived from the network connectivity state and it is essential to set up properly WPNC processing at each node. The data payload in WPNC network uses a common signal space of mutually interacting signals superposing on the receive node antenna. There are no orthogonalized communication links that would allow traditional control-data signaling based approaches to determine the network state. The procedure where each node establishes a complete picture of the network state must be performed before the payload phase such that the superposing non-orthogonal pilot signals fully respect the WPNC paradigm. This paper proposes a distributed consensus-based estimator of the network state which operates on a common signal space shared by all nodes in the network. The algorithm allows each node to find the global network state based only on local neighbor superposed pilot observation.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121199890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The satellite IoT networks can cover areas that are not reachable by the wired and the wireless terrestrial networks. A Self-Organizing Time Division Multiplexing Access (SOTDMA medium access control (MAC) protocol is used for the Satellite Automatic Identification System (S-AIS). This paper analyzes and derives the detection probabilities of the ship vessels from a AIS satellite for the S-AIS with a Decollision Algorithm (S-AIS-DA) as well as with Spot Beam (S-AIS-SB) or both (S-AIS-DA-SB). A simple probabilistic model is used to capture the packet error ratios in these schemes. Numerical results show that the performance gains in the number of ship vessels that can be detected can be up to 132% for the S-AIS-DA scheme that can decode up to 4 packets over a basic S-AIS scheme and up to 131% for the S-AIS-DA-SB scheme that can decode up to 4 packets and with 6 spot beams over the S-AIS-SB scheme. The percentage losses of number of ship vessels that can be detected for these schemes with packet loss ratios as compared with these schemes without packet loss ratios are about 1.1%, 1.1% and 2.9% for a decollision algorithm that can decode in an access slot up to one, two and three packets, respectively. On the other hand, the percentage drops in the detection probabilities of the S-AIS-DA scheme with packet error ratios over that of the S-AIS-DA scheme without packet error ratios and the S-AIS-DA-SB scheme with packet error ratios over that of the S-AIS-DA-SB scheme without packet error ratios for detecting up to 3 packets are 4.6% and 3.8%, respectively.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126714748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The performance of M-DCSK scheme is analyzed over PLC channels where background, impulsive and phase noise exist. Simulation results verifiy the accuracy of the derived theoretic performance. Due to the inner properties of chaotic carrier, M-DCSK shows good robustness against multipath fadings and phase noises, which are very common in PLC channels. Besides, comparing with the traditional direct sequence M-ary differential phase shift keying (DS-MDPSK) scheme, M-DCSK can achieve better bit error rate (BER) performances.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121134505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this scenario, we propose an optimal spectrum sensing policy for opportunistic spectrum access/energy harvesting under both the PU collision and energy causality constraints. PU channels can have different traffic patterns and exhibit distinct idle/busy frequencies, due to which the spectral access/energy harvesting opportunities are application specific. Secondary user (SU) collects traffic pattern information through observation of the PU channels and classifies the idle/busy period statistics for each channel. Based on the statistics, we invoke a stochastic model for evaluating SU capacity by which the energy detection threshold for spectrum sensing can be adjusted with higher sensing accuracy. To this end, we employ the duty cycle model obtained by the ratio of average harvested energy and energy consumption rates. We demonstrate the effectiveness of the proposed stochastic model through comparison with the optimal one obtained from an exhaustive method.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128940238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In visible light systems, LEDs or LDs in transmitters have small dynamic range of input signal magnitude for linear operation and the bias current must be carefully set to consider the maximum allowable forward current of LEDs or LDs, to reduce magnitude distortion and to control signal clipping. The OFDM enables the limited frequency bandwidth of LEDs or LDs to be fully-used and the CAZAC equalization drastically reduces magnitude fluctuation of OFDM time-domain signal. We found that one CAZAC sequence in cooperation with IFFT process converts the PAPR of the M-Quadrature Amplitude Modulation (QAM) OFDM signal into the PAPR of an M-QAM single-carrier signal. This fact is our new discovery. Moreover, since the CAZAC equalization has potential capacities of frequency diversity effect, the system has an advantage in improvement of the BER performance under frequency selective fading environments, which also includes the frequency-dependent attenuation due to the frequency response of LEDs and LDs. Furthermore, we verified for 16QAM-OFDM and 16PSK-OFDM, and confirmed that the communication distance is much extended by the CAZAC.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115483242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The HetNet is a system in which pico base stations are placed in a macrocell and shares frequency resources with a macro base station. In the HetNet, the offloading of traffic to the pico base stations is limited since the transmission power of the macro base station is large. To achieve better spectrum efficiency with offloading, NOMA HetNet is proposed. In the proposed scheme, the desired signal is extracted with joint detection to realize offloading to a pico base station. Numerical results obtained through system level simulation show that NOMA doubles the total throughput by enhancing traffic offloading.","PeriodicalId":320208,"journal":{"name":"2017 23rd Asia-Pacific Conference on Communications (APCC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114248773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
