摘要
针对我国高分辨率遥感数据超高速传输的需要,提出了符号速率930 MS/s的16APSK信号解调器设计。根据信号模型,设计了解调器信号处理方案,重点分析了时钟同步算法、载波同步算法和信号均衡算法,采用VHDL语言对设计的方案进行了实现。在硬件平台上进行了调试和解调性能的测试,测试结果表明,解调器的解调损失小于1dB,满足实际工程需要。
The demodulator design for 16APSK signal with symbol rate of 930 MS / s is proposed to meet the requirements of highresolution remote sensing data transmission in China. First of all,the signal processing scheme of the demodulator is designed according to the signal model. Then the paper focuses on analyzing the clock synchronization algorithm, carrier synchronization algorithm and signal equalization algorithm. The designed scheme is implemented by the VHDL and debugged on the hardware platform. Finally the demodulation performance test is performed. The results show that demodulation loss is less than 1 dB,which meets actual engineering needs.
