摘要:

基于伪随机交织器,提出了一种比特交织编码调制-迭代检测(BICM-ID)下星座映射的新规则,并设计了新的8相移相键控(8PSK)星座映射. 通过分析和计算机仿真,比较了各种8PSK星座映射性能,加性高斯白噪信道下的性能仿真结果表明,根据新规则设计的8PSK星座映射好于其他星座映射.

Abstract:

A new signal labeling designed criterion is proposed for bit interleaved coded modulation with iteratively decoding (BICM-ID) when using pseudo interleaver. A new eight phase shift keying (8PSK) signal labeling is designed based on it. Comparative study of different labeling is done through analysis and computer simulation. The results under AWGN show that the new designed signal labeling outperforms the others.

Key words: bit interleaved coded modulation with iteratively decoding, eight phase shift keying, signal labeling
