在这封信中，我们研究了级联瑞利衰落信道上中继选择的合作分集。特别地，我们分析了具有解码转发（DF）协议的协作车载网络中继选择方案的性能。只有满足优点指标的“最佳”继电器才会被选中。我们忽略源(S)和目的地(D)之间的直接传输，并假设目的地完全了解S→R和R→D信道增益。从中断概率的角度研究了底层方案的性能，并研究了其可实现的分集顺序。
In this letter, we investigate cooperative diversity with relay selection over cascaded Rayleigh fading channels. In particular, we analyze the performance of a relay selection scheme for cooperative vehicular networks with the decode-and-forward (DF) protocol. Only the “best” relay, which satisfies an index of merit, is selected. We ignore the direct transmission between the source (S) and its destination (D), and assume that the destination has perfect knowledge of the S → R and R → D channel gains. We study the performance of the underlying scheme in terms of outage probability and investigate its achievable diversity order.
