Abstract

Keywords—wireless communication, network coding, diversity gain, relay Abstract—Complex field network coding (CFNC) is a new network coding approach proposed to improve network throughput and achieve full diversity gain in wireless networks. In this paper, a novel complex-field network coding scheme is developed based on cooperative communication. Different from traditional network coding scheme, transmissions are not restricted to binary symbols. The proposed scheme can achieve throughput to approximately XXX symbols per source per channel use. Theoretic analysis demonstrate that, the improved CFNC scheme can obtain the same network throughput and diversity gain as CFNC, while it can decrease the transmission delay of source symbols, and reduce the detection complexity of destination.
