目前自动和自适应均衡器的局限性源于前馈横向滤波器的使用。这些缺点可以通过使用反馈横向滤波器,即逆滤波器来消除,但这只适用于有限的使用,因为它可能是一个不稳定的电路。结果表明,在反滤波器中采用模算法可以完全消除不稳定的可能性,并提出了一种非常简单的自动或自适应均衡系统。给出了模逆滤波器的一些有趣的性质。
The limitations of present automatic and adaptive equalisers stem from the use of feedforward transversal filters. These drawbacks may be obviated by using a feedback transversal filter, the inverse filter, but this is only suitable for limited use since it can be an unstable circuit. It is shown that modulo arithmetic may be used in the inverse filter to eliminate completely the possibility of instability, and a very simple automatic or adaptive equalisation system is presented. Some interesting properties of the modulo inverse filter are included.
