摘要
在慢衰落信道条件下,为提高误码率性能,提出一种比特交织编码协同方案,用户或协同伙伴的编码数据,相邻两帧的打孔或者未打孔部分分别通过比特交织器进行交织,然后通过BPSK调制并按发送方案和划分时隙进行发送。推导了比特交织编码协同方案在慢衰落信道条件下的成对错误概率,仿真证明,此方案能够获得三阶完全分集。
A bit interleaved ceded cooperation （BICC） scheme is proposed over slow-fading Rayleigh channels. In this scheme, encoded bits of the user or the partner are partitioned with two parts; each part is interleaved between the continuous two frames, mapped on a BPSK constellation and then transmitted on the allocated time slots. The pairwire error probability of BICC scheme is derived. Simulations show that the coded cooperation with bit interleaver can achieve three full diversity over slow-fading Rayleigh channels.
