基于复数域网络编码的D2D传输方案设计
Design of D2D Transmission Scheme Based on Complex Field Network Coding
摘要
Abstract
Terminal users of device-to-device (D2D) communication inevitably will be interfered by cellular users while using multiplexing cellular network spectrum to improve spectrum efficiency. A D2D transmission scheme based on complex field network coding is proposed in this paper. Specifically, as the D2D user multiplexes cellular downlink spectrum, the cellular base station and D2D sender can be regarded as two independent sources, and meanwhile the cellular user as relay node. Moreover, the cellular user encodes the detected cellular signals and D2D signals by complex field network coding, and the D2D receiver can recover D2D signals by adopting maximum likelihood multiuser detection to eliminate cellular signal interference. Theoretical analysis and simulation results show that, compared with traditional D2D transmission schemes, the proposed scheme can improve system achievable rate evidently and reduce symbol error probability, simultaneously ensuring the elimination of cellular signal interference.关键词
