Statistical priority-based multiple access protocol (SPMA) can be applied to these systems by virtue of its high-reliability and low-delay characteristics. In this paper, we propose a non-preemptive M/M/1/K queuing model to analyze the performance of different priority traffic in SPMA in terms of the average packet loss rate and the average packet delay. Firstly, we take no account of threshold of channel occupancy. Through analyzing the process of state transition, we can get the steady-state probability of the model. The loss rate and delay can be obtained based on the steady-state probability. Then, we extend to the case in consideration of threshold. Extensive simulations demonstrate that loss rate values and delay values obtained from our analytical model closely match the simulation results under various offered loads. More importantly, our model can enable designers to obtain a better understanding of the effect of protocol parameters on the performance of SPMA.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124291202","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}

Moreover, massive multiple-input multiple-output (MIMO) technology over satellites has received a great deal of interests. To solve the problem of pilot collision in the crowded massive MIMO system for SIN, a joint random pilot and multi-slot access (JRPMSA) protocol is proposed. Our JRPMSA protocol allows the failed user equipments (UEs) to reselect a pilot from the remaining pilots in multi-slots, i.e., the pilots that are not selected by any UE or selected by more than one UE in the initial step. The random access satellite estimates and buffers the channel response on each pilot of each UE in multi-slots. By utilizing the and-or tree theory, we analyzed the performance of the JRPMSA protocol, mainly focus on the access failure probability and uplink throughput. Simulation results shows that the proposed JRPMSA protocol can obviously decrease the access failure probability and increase the peak throughput.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122446308","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}

We present the ideas in two-user time-varying interference channels with limited receiver cooperation. We assume that the receivers are connected to a central processor via wired cooperation links with individual limited capacities. Our SNC scheme determines the precoding matrices of the transmitters so that the transmitted signals are aligned at the receivers. The aligned signals are then decoded into linear combinations of messages by physical-layer network coding strategy. The key idea of our scheme is to ensure that independent linear combinations of messages, also known as network-coded messages, can be decoded at the receivers. Hence the central processor can recover the original messages of the transmitters by solving the linearly independent equations. We prove that our SNC scheme achieves full degrees of freedom (DoF) by utilizing signal alignment and physical-layer network coding. Simulation results show the DoF achieved by our SNC scheme almost doubles that by the orthogonal transmission scheme in two-user time-varying interference channels with limited receiver cooperation. The performance improvement of our SNC scheme mainly comes from efficient utilization of the signal subspaces for conveying independent linear combinations of messages to the central processor.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126481695","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}

Many analytical models have been proposed to evaluate the MAC layer performance of status message transmission based on the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol. However, they either fail to consider lifetime of status messages or assume a random arrival of status messages. In addition, all these models are based on the assumption that distribution of MAC layer states is unchanged with the time, which is not applicable in the periodic broadcast schemes. In this paper, we propose an analytical model where constant arrival intervals and lifetime expiration of messages are simultaneously considered. Moreover, we discard the assumption of unchanged states distribution by introducing a pure death process. The proposed model is verified with simulation data obtained by NS2, and results showed that proposed model can accurately capture the reception probability, collision probability, and discard probability of periodic broadcast messages.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"2009 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125603133","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}

However, due to the rapid changes of the main channel and the feedback delay of the channel state information (CSI), the transmitter obtains outdated CSI, and the outdated CSI leads to the outdated optimal transmit antenna. In order to improve the security of the system based on outdated CSI, in this paper, we propose a deep reinforcement learning framework of Deep Q Network (DQN) to predict the optimal transmit antenna in the multiple input multiple output (MIMO) wiretap channel. The legitimate receiver receives the pilot signals from each transmitting antenna, and the signal-to-noise ratio (SNR) of the pilot signals transmitted by each transmitting antenna can be obtained through maximal ratio combining. And then the legitimate receiver uses the DQN to predict the transmitting antenna at the next moment according to these SNRs. The simulation results show that DQN algorithm can effectively predict the optimal antenna at the next moment, and reduce the secrecy outage probability of MIMO wiretap system, compared with the traditional algorithm.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"181 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133847639","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}
