Phase sweep space - time bit interleave coded modulation 掃相空時(shí)比特交織編碼調(diào)制
The performance of tcm over awgn channel is perfect but it is bad over fading channel . there is an effective method to solve this problem that combines interleave technique with coded modulation to get the gain of performance over fading channel . this paper is about a new coded modulation technique ? ? bicm ( bit interleaved coded modulation ) and bicm _ id ( bicm with iterative decoding ) , and their performance of bit error rate in different conditions 本文研究的就是一種將交織技術(shù)與編碼調(diào)制相結(jié)合的新的編碼調(diào)制方式? ?比特交織編碼調(diào)制( bicm , bitinterleavedcodedmodulation ) ,和引入迭代反饋?zhàn)g碼的比特交織編碼調(diào)制( bicm _ id , bicmwithiterativedecoding ) ,及它們?cè)诓煌诺罈l件下的性能。
