介绍了基于TMS320C6711 DSP的HF信道8PSK信号解调方案。论述解调算法中用到的平方根卡尔曼判决反馈均衡器(DFE)、判决反馈式锁相环(DFPLL)等关键技术。
The HF channel 8PSK signal demodulation scheme based on TMS320C6711 DSP is introduced. The key techniques of square root Kalman decision feedback equalizer (DFE) and decision feedback phase locked loop (DFPLL) used in the demodulation algorithm are discussed.
