Abstract

The modulo-inverse prefilter is a nonlinear digital filter that contains a standard linear infinite impulse response part and a nonlinear modulo number operation in the feedback that constrains output. This filter has been used in data transmission systems as a transmit-end equalizer to combat intersymbol interference on dispersive channels because it can act as the pseudo-inverse of any finite infinite impulse response channel function F(z). The author shows that since its output appears very white across the Nyquist band, independent of input, it has applications as a data scrambling device or whitener. This application is possible because it is very difficult to find the correct 'key' or filter coefficients by simply observing the incoming data stream, and there are no synchronization problems between the transmitter and receiver because the receive end is self-synchronizing.<>

采用模逆预滤波器作为数据置乱装置
模逆预滤波器是一种非线性数字滤波器,它包含一个标准的线性无限脉冲响应部分和一个约束输出的反馈中的非线性模数运算。由于该滤波器可以作为任意有限无限脉冲响应信道函数F(z)的伪逆,因此在数据传输系统中用作发送端均衡器来对抗色散信道上的码间干扰。作者表明,由于它的输出在奈奎斯特带上看起来很白,独立于输入,它可以用作数据置乱装置或增白器。这种应用是可能的,因为很难通过简单地观察传入的数据流来找到正确的“密钥”或过滤系数,并且由于接收端是自同步的,因此发射器和接收器之间没有同步问题。
