In this paper, an enhancement in SM scheme is proposed by innovative usage of quadrature amplitude modulation (QAM) to add layers which fully exploit both the signal and spatial domains. Layered spatial modulation (LSM) controls the preset rotated signals with normalized amplitudes to classify the layers and to identify the transmitted symbols at the transceiver by completely avoiding inter-channel interference (ICI). High spectral efficiency can be achieved with the addition of only one transmit antenna for each layer by the LSM scheme. Simulation results show that the proposed method has significant improvement in spectral efficiency and bit-error-rate (BER) performance as compared to other MIMO schemes.","PeriodicalId":285172,"journal":{"name":"2019 28th Wireless and Optical Communications Conference (WOCC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125158177","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}

Although the fifth generation (5G) communication systems provided high rate data services in HST, yet it restricted for the signal bandwidth and spectrum license. In order to enhance the HST communication performances, optical communication technologies are applied in HST. Hence, in this work, we focus on the optical wave as transmission carrier in HST communication. In communication process, experienced frequent handover, limited coverage of base station and changed of environment factors are most challenges. For overcoming those obstacles, several optical communication systems are proposed in recent year. Several researchers are proposed optical wireless communication (OWC) systems which are optimized the communications barriers in HST. Beside, the optical fiber communication (OFC) systems are used to strengthen the capacity of HST communication. Moreover, plentiful experiments are established for studied the optical communication performances, which are set up consisted of car is replaced with train, simulated HST scenario in lab and tested in reality HST scenario.","PeriodicalId":285172,"journal":{"name":"2019 28th Wireless and Optical Communications Conference (WOCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130359757","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 architecture, the transmit and receive sides of HSR system are both equipped with distributed antennas, then base stations (BSs) communicate with users via mobile relays (MRs) on the top of train. Thus, the data will be buffered when the wireless transmission rate can not satisfy the requirement of data arrival rate. In this paper, we focus on the efficient power allocation method with buffer and delay constraint on the basis of predicted path loss characteristic in downlink HSR communications. Firstly, the relationship between the data arrival rate and instantaneous wireless transmission rate is analyzed where BSs transmit with constant power. Secondly, the transmit power optimization problem with the requirement of buffer size and delay is formulated. The optimal power allocation scheme can be obtained through Lagrangian dual method. Simulation results demonstrate that the proposed power allocation scheme can achieve a lower consumed power and avoid data overflow and infinite delay as well.","PeriodicalId":285172,"journal":{"name":"2019 28th Wireless and Optical Communications Conference (WOCC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121525381","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}

Each cooperative vehicle uses its own GPS receiver to estimate its position. And inter-vehicle position information is obtained by the Dedicated Short-range Communication (DSRC). This proposed method includes two processes. Firstly, the GPS positioning information of cooperative vehicles are collected to get the positioning matrix. Then the EKF is applied to the matrix to further improve the positioning accuracy. In the simulation, we analyze the impact of different numbers of neighbor vehicles on positioning accuracy and the performance of the proposed method has been verified.","PeriodicalId":285172,"journal":{"name":"2019 28th Wireless and Optical Communications Conference (WOCC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116971770","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}

Motivated by the requirement of low complexity and latency in 5G, researchers are keen to study efficient construction of polar codes. In this paper, inspired by the idea of relaxed polar codes, we study the relaxation of polar codes, and propose an efficient construction method for relaxed polar codes. By relaxing part of polarization units, the proposed method can help polar codes significantly reduce the encoding and decoding complexity as well as decoding latency with no BLER performance loss. Meanwhile, the proposed relaxed polar codes shows better BER performance due to the reduction of the impact of error propagation.","PeriodicalId":285172,"journal":{"name":"2019 28th Wireless and Optical Communications Conference (WOCC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117011753","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 paper we introduce the multi-color communication module and the architecture of our proposed multi-color MIMO system model.

To solve these problems, a conflict-free clustering-based MAC protocol is proposed in this paper which employs TDMA-based deterministic slot assignment to resolves access collisions and to ensure bounded delay and centralized access mechanism for efficient resource management. Mitigation of merge collisions is proposed through disjoint slot assignment and channel distribution with respect to direction of node mobility, whereas, location and mobility awareness of nodes helps in cluster formation and resolve packet conflicts due to hidden terminals. Our simulation results show that the proposed protocol performs better than IEEE 802.11p MAC and TCMAC protocols in both urban and highway traffic scenarios.","PeriodicalId":285172,"journal":{"name":"2019 28th Wireless and Optical Communications Conference (WOCC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122379127","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}

To address this issue, we proposed a novel weighted Neumann series (WNS)-based LMMSE detection to minimize the error between the exact matrix inversion and the WNS-based matrix inversion. Moreover, the optimal weights are obtained according to on-line learning basis.
