To decode a received codeword correctly with exactly matching a list size, a just right list size is required to be estimated. In this paper, based on the reliability degree of the codeword decoded by the successive-cancellation (SC) decoding, a list estimation method has been proposed for a poor case of channel environments, where the log-likelihood ratio (LLR) from SC decoding output is utilized to estimate a list size. The list estimation aids the polar code decoding and achieves admirable results in performance.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"64 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":"114775912","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, the geometric stochastic modelling method for spatial consistency is implemented. And the specific modelling procedure is provided. By modifying the mmWave channel model in ITU-R, the spatial consistency is applied into the model. On the basis of it, the changes of cluster delays and angles as mobile station (MS) moving under a certain trajectory are researched. For comparing, the same research is operated on the platform without spatial consistency. It can be observed that delays and angles of cluster will change continuously and obviously with the trajectory. These analysis results can give insight into the performance of mmWave communication system.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"20 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":"116985931","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, it is difficult to significantly increase the anti-jamming results because of the growing crowded spectrum in wireless communications. Orbital momentum angular (OAM) provides a new mode dimension for anti-jamming without consuming extra power and frequency resources in CRNs. In this paper, we propose the mode-frequency hopping (MFH) scheme, which jointly uses the mode hopping and the traditional FH scheme for anti-jamming to significantly increase the capacity of secondary users (SUs). We derive the false alarm probability and transmission outage probability for CRNs under our proposed MFH scheme. Then, based on the two derived probabilities, we calculate the capacity of SUs under the MFH scheme. Numerical results show that our developed MFH scheme can achieve better anti-jamming results as compared with the traditional FH scheme in CRNs.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"1 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":"129379310","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}

Different from the traditional spatial modulation schemes, the legitimate channel state information is utilized to convey part of information bits instead of amplitude phase modulation (APM) constellation. By this way, the normal transmit signals will become artificial noise to the eavesdropper, and it is impossible for the eavesdropper to know the legitimate channel state information. Consequently, the secrecy transmission could be achieved. Moreover, all transmit power is used to transmit the legitimate signals without any energy waste. The secrecy rate is analyzed, and the numerical results show that the new AN-SM scheme could achieve high secrecy rate.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"8 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":"127224088","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}

Compared with the fully-connected structure in hybrid MIMO systems, the adaptively-connected structure requires a significantly reduced number of analog phase shifters (APSs) and no radio frequency (RF) adder. In this paper, we focus on the multi-user massive MIMO system with adaptively-connected structure and propose a compressive sensing (CS) based method to design hybrid beamforming. The RF combiner for each user is independently designed based on the decomposition of the channel. By exploiting the sparse structure of RF precoder, we develop an iterative greedy algorithm to jointly design the RF precoder and baseband precoder, aiming at maximizing the effective signal power as well as eliminating the multi-user interference. Moreover, upper bound of the achievable sum rate for the proposed scheme is derived. The numerical results demonstrate that the proposed scheme can approach the performance of fully-connected scheme and achieve a higher sum rate than the existing schemes in both Rayleigh fading channel and millimeter wave channel.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"7 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":"130595712","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}

Due to the wide range of serviced ground users, a large number of UAVs need to be deployed. In this paper, we study a multi-UAV downlink communication system with the UAVs acting as the aerial mobile base stations, and investigate the probability of successful transmission between the UAV and its served users, with consideration of both energy availability and mobility effects. We propose the optimal control law based on a discrete-time mean field game (MFG) with power control and velocity control. Furthermore, the optimal controls generate an almost surely asymptotic Nash equilibrium according to the estimate of population state average, meaning that the long time average cost reaches its minimum.

The transmit power of the secondary users (SUs) is limited by the predefined interference threshold to guarantee the quality of service (QoS) requirement of the primary users (PUs). We adopt the max-link relay selection scheme, which can improve the secrecy performance by selecting the best link among all available source-to-relay and relay-to-destination links. Moreover, a closed-form expression of the secrecy outage probability is derived by modeling the state transition of the buffer as a Markov chain. Monte Carlo simulations validate the theoretical analysis. The findings of this paper demonstrate that the outdated CSI degrades the secrecy outage performance, but optimizing several parameters can improve the system secrecy performance significantly.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"1 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":"123311514","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}
