摘要
根据恒幅窄带原理ＤτＡＧＣ（Ｉ／Ｄ）抗干扰方法，导出一种用于处理离散基带信号的ＤτＡＧＣ递推算法，并将此算法用于数字信道的ＤＦＥ自适应均衡．计算机模拟实验表明，ＤτＡＧＣ算法能有效地抑制脉冲干扰、压缩动态范围，与固定时间常数ＡＧＣ算法相比，采用ＤτＡＧＣ算法的ＤＦＥ均衡器误码率明显降低．
According to the antiinterference theory of constant amplitudenarrow band and corresponding antiinterference methods. The authors obtained a DτAGC iterative algorithm for processing baseband signal,and applied it to the equalization of digital communication channel.Computer simulation indicated that DτAGC algorithm be efficient in both restraining impulse interference and reducing dynamic range of signal.Comparing with the fixedτAGC algorithm,the error rate of equalization with DτAGC algorithm is reduced considerably.
