PSP LD-Based Low Complexity Detection Algorithm for M-ary CPM Signals
Bing Wang, Jinle Zhu, Qiang Li · 2018
In this paper, we propose a new Laurent decomposition based low complexity detection scheme for M-ary continuous phase modulation (CPM) signals. By introducing per survivor processing (PSP) algorithm in the demodulation of Laurent-based CPM signals, the proposed scheme simplifies the trellis structure, which reduces the detection complexity of CPM signals. Numerical results reveal that the proposed algorithm can significantly reduce the detection complexity at the price of slight bit-error-rate (BER) disgrace as compared with the conventional detection schemes.
