一种中继网络中分布式空时分组码的设计
A New Design of Distributed-Space Time Block Codes in Relaying Networks
摘要
Abstract
In the traditional use of Distributed-Space Time Block Codes(D-STBC) in the relay system, matrix relay nodes generated code words need to control message overhead without changing the relay node number, which is not suitable to the practical communication scenarios.In order to solve the problem, we propose a new method of D-STBC coding.The method introduces D-STBC in traditional multiple input multiple output system and uses the AF forward agreement.The Relay nodes don't require the control message when generating code word matrix and cooperating with other nodes.Therefore, the adaptability of the communication system of collaboration and performance of the system can be improved.Finally, the MATLAB simulation results show that the method has more superior performance in full diversity and full rate conditions with low decoding complexity.关键词
