基于多符号检测的CPM信号解调技术研究

Studies of demodulation technique of CPM based on MSD

对连续相位调制(CPM)系统进行了分析,研究了基于多符号检测原理的CPM信号解调技术,在AWGN信道下以二进制CPM为例给出了不同检测长度下系统的解调性能.结果表明,非相干多符号检测(MSD)算法在损失很少误码性能的前提下可以有效降低解调复杂度,便于工程实现.

Based on the analysis of continuous-phase-modulation system, demodulation tech- nique of CPM based on MSD was discussed, and the simulation results of different detection length which took binary CPM system in AWGN as instance was given. The simulation re- sults showed that non-coherent MSD had a good balance of performance and complexity, and was feasible of applying to engineering application.
