Compared with conventional iterative DPSK signal demodulation/decoding based on the BCJR (Bahl Cocke Jelinek Raviv) algorithm,the new algorithm results in considerably low decoding cost yet can achieve nearly the same performance.

• 与基于BCJR(Bahl Cocke Je linek Raviv)的TurboDPSK解调 /译码算法相比 ；它可以大大降低运算复杂度 ；减少迭代译码过程中所需的存储空间 .；仿真结果表明；采用这种新的迭代解调 /译码算法可以获得和基于BCJR的迭代解调 /译码算法几乎一样的性能
