ABSTRACT:
A blind equalization method and adaptive filter device is presented which provides for optimal performance with minimal computational complexity. Recognizing that all realizable filters have residual noise characteristics, the optimization of a hard-limiter adaptive filter is determined in dependence upon an estimate of this noise characteristic. The filter can be further adapted and optimized in dependence upon measured values of the filter's noise characteristics in its actual operating environment.
