摘要
为了降低连续相位调制(CPM)系统的解调门限,减少复杂编码给系统带来的运算开销,保证系统结构简单高效,提出一种适用于CPM调制方式的串行Turbo码方案。该方案利用CPM调制本身的累加结构作为串行Turbo码的内码,利用卷积码作为外码。仿真表明,该方案的误码率优于并行Turbo编码CPM约3 dB。
In order to reduce the threshold of Continuous-phase modulation, to decrease the computation expenses caused by complicated code, and to simplify the structure, the paper proposes a serial Turbo code for CPM. The serial Turbo code CPM uses the accumulate frame of CPM as its inner coder, and convolution code as its outer code. Simulations demonstrate that this method is about 3 dB better than the parallel Turbo code CPM.
