摘要: 本文从理论上分析了HF串行数字传输系统抑制多音干扰的性能;求出了系统中自适应均衡器的最佳系数和最小均方误差表达式;分析了多音干扰对均衡器收敛性的影响;指出HF串行数字传输系统中的自适应均衡器既能跟踪信道快速变化,又具有强的抑制多音干扰的能力。Abstract: The multi-tone interferences suppression in HF serial data transmission systems is analysed. Analytic expressions for the tap weights and minimum mean square errors of adaptive equalizer in HF serial systems are obtained. The rate of convergence of equalizer in the presence of multi-tone interferences is analysed. The analytic and simulated results indicate that the equalizer in HF serial systems can not only track the rapid variation of HF channel but also suppress the multi-tone interferences perfectly.
