ABSTRACT (UALXhnur 200 words)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 exidstence of a time-varying misadjutment 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 perfor-
