摘要

提出了一种编码交错连续相位调制(CPM)波形的迭代(turbo)译码方法。该发射机包括速率为2/3的卷积编码器，其后是交织器和8进制连续相位调制器。在接收端，软输出卷积码的后验概率算法和CPM波形迭代地改进它们的概率估计。目前的仿真结果表明，与栅格编码CPM (TCCPM)相比，信噪比提高了2.5 dB(在10/sup -5/误码率下)，带宽效率为1.24 bps/Hz，达到99%。探测器的复杂性大约是TCCPM系统的4.5倍。

Turbo detection of coded continuous-phase modulations

Iterative (turbo) decoding of a coded, interleaved continuous-phase modulated (CPM) waveform is presented. The transmitter consists of a rate-2/3 convolutional encoder followed by an interleaver, and an 8-ary continuous phase modulator. At the receiver, soft output a posteriori probability algorithms for the convolutional code and the CPM waveform iteratively refine their probability estimates. Current simulation results show a 2.5 dB SNR improvement (at 10/sup -5/ bit-error rate) over trellis-coded CPM (TCCPM) with a 99% bandwidth efficiency of 1.24 bps/Hz. The detector has a complexity of approximately 4.5 times that of the TCCPM system.
