The Performance of Adaptive Equalization for Digital Communication Systems Corrupted by Interference

Abstract

This paper analyzes the effects of interference on the steady-state performance of several popular adaptive equalization algorithms. It is shown that adaptive equalizers based on the linear equalizer structure have a built-in capability to reject narrowband interference, however performance deteriorates as the bandwidth of the interference increases. The existence of a time-varying misadjustment component in the adaptive equalizer weight vector is shown to affect the interference cancellation properties. In addition, simultaneous multipath propagation and interference is investigated. These effects on the performance of the adaptive linear equalizer are especially important to applications where intentional or unintentional interferers may be encountered.
