[电气工程与系统科学] 误码传播对协作系统误码性能的影响 具有最佳中继选择方案的通信 [推广有奖]

摘要翻译：
本文研究了存在从角色到目的地的错误传播时，具有最佳中继选择方案的协作通信系统的误码性能。首先推导了在M个继电器中选择最佳继电器时的误差传播表达式。通过计算机仿真验证了推导出的端到端误码率表达式。结果表明，在错误传播情况下，最佳中继选择不像理想译码那样保证M+1分集阶数。另外，继电器的门限选择对系统的误码性能有重要影响。

英文摘要：
  In this paper, error performance of the cooperative communication systems with the best relay selection scheme is investigated in the presence of error propagation from role to destination. The error propagation expression is derived firstly when the best relay is selected within M relays. The derived end-to-end BER expression is verified with the computer simulations. It is shown that the best relay selection does not ensure M+1 diversity order under the error propagation unlike perfect decoding. In addition, the threshold selection for the relays has dominant effect on the error performance of the system.
