基于DVB-C具有增益补偿的自适应均衡器设计

Design of an Adaptive Equalizer Combined with Gain Compensation Based on DVB-C

采用一种具有增益补偿的自适应均衡器的设计方法,可直接利用均衡器产生的误差自适应地补偿输入信号,不需要单独的自动增益控制电路,有效地减小了QAM解调器的复杂度。MATLAB系统仿真结果表明,采用这种方法设计的自适应均衡电路能够在接收端纠正传播过程中的信号畸变。

This paper presents an adaptive equalizer combined with gain compensation. Without traditional AGC, the approach using equalizer＇s error to compensate the input signal reduce the complication of the QAM receiver system efficiently. The results of MATLAB system simulation demonstrate the proposed adaptive equalizer can compensate the channel distortions
