将RLS分数间隔均衡器(FSE)用于流星突发通信系统中抗码间干扰,与波特间隔均衡器(SRE)相比,分数均衡器具有对采样相位选择的不敏感,且能够补偿固有的信道畸变的优良性能。理论分析和仿真结果表明,分数间隔均衡器和波特间隔均衡器具有几乎相同的收敛速度,但分数间隔均衡器比波特间隔均衡器具有较小的均方误差,均方误差性能可以改善1-2个数量级。另外,分数间隔均衡器的均方误差性能受信噪比的影响要明显小于波特间隔均衡器。
Using RLS fractional equalizer (FSE) for anti-code interference in meteor burst communication systems, the fractional equalizer is insensitive to sampling phase selection and compensates for intrinsic The excellent performance of channel distortion. Theoretical analysis and simulation results show that the fractional-interval equalizer and the baud-interval equalizer have almost the same convergence rate, but the fractional-interval equalizer has smaller mean square error than the port-spaced equalizer and the mean-square error performance can be improved by 1 -2 orders of magnitude. In addition, the mean square error performance of fractional-interval equalizers is significantly less affected by the signal-to-noise ratio than the port-spaced equalizers.
