短波特定信号接收处理仿真及实现

Shortwave Specific Receiving Signal Processing Platform Design

针对MIL-STD-188-110C附录C定义的信号波形,仿真了其接收处理过程。重点探讨了同步捕获、符号定时、载波频偏估计和同步跟踪算法对该信号解调效果的影响,并结合Xilinx ZCU102评估板SoC架构芯片设计仿真基于信号辅助序列的接收处理平台。最后,对该信号波形在CCIR(International Radio Consultative Committee,CCIR)标准短波信道下的性能进行仿真,由仿真结果可知该接收处理方案在中等短波信道下解调误码率可到10-4,保证了信号解调的有效性。

This paper simulates the receiving process of the signal waveform defined in Appendix C of MIL-STD-188-110C.The influence of synchronization acquisition,symbol timing,carrier frequency offset estimation and synchronization tracking algorithm on the demodulation effect of the signal is discussed,and a receiving and processing platform based on signal auxiliary sequence is designed and simulated by combining Xilinx ZCU102 evaluation board SoC architecture chip.Finally,the performance of the signal waveform in the International Radio Consultative Committee(CCIR)standard short wave channel is simulated.The simulation results show that the bit error rate of the receiving processing scheme in the medium short wave channel is 10-4,which ensures the feasibility and effectiveness of receiving demodulation.
