摘要
文章提出了一种基于Viterbi算法的短波SFH／CPM系统差分相位检测（DPD）的解调方案，运用Matlab建立了短波SFH／CPM系统模型，并在此模型上对该解调方案的误比特率进行了数值仿真。其仿真结果表明：DPD解调方案的误比特率可以达到10^-5～10^-6，能满足短波信道性能的需求。
In this paper,differential phase detection （DPD） based on Viterbi algorithm is proposed as a demodulation method in shortwave SFH/CPM system. The system model of shortwave SFH/CPM is constructed through Matlab simulation tool, and BER performance of this algorithm is simulated for differential parameters. The simulation results show that the BER can be 10^-5～10^-6 and satisfy the requirement of shortwave frequency hopping communication system.
