摘要: In this paper, we propose a low-complexity iterative soft detection algorithm for bit interleaved coded continuous phase modulation (CPM). The reduction of complexity is obtained by using index at the receiver side which different from one used transmitter side. This difference balanced thanks to soft-input soft-output (SISO) coherent CPM demodulator based on per survivor processing (PSP) technique. Compared state art, error rate performance improved. We also show that our converges close maximum posteriori (MAP) algorithm, with few additional iterations.
