摘要

研究了随机穿刺的变速率turbo比特交织编码调制(turbo - bicm)的性能。导出了可变速率Turbo-BICM的联合- bhattacharyya速率阈值。对于AWGN信道,确定了该速率阈值的封闭近似形式,并证明可以很好地预测Turbo-BICM迭代解码性能。

Variable-rate turbo bit-interleaved coded modulation
This paper studies the performance of variable-rate turbo bit-interleaved coded modulation (Turbo-BICM) with random puncturing. A union-Bhattacharyya rate threshold for the variable-rate Turbo-BICM is derived. A closed form approximation of this rate threshold is determined for an AWGN channel and shown to predict the Turbo-BICM iterative decoding performance very well.
