Abstract
In this paper, we study ways an equalizer can be used to mitigate the degrading effects of interference on the performance of radio communications systems. The equalizer is adaptive and is otherwise used to compensate for channel distortions leading to intersymbol interference. The channel is modeled as a time-dispersive Gaussian noise channel, occasionally corrupted by non-Gaussian interference. The non-Gaussian interference is modeled as a constant-wave sine interference. The leastmean square algorithm is used to implement the adaptive process of the equalizer and is appropriately modified so as to help the equalizer compensate for the sine interference also. Computer simulations are used to perform trade-off analyses and performance evaluations. The results of the study are shown using learning curves describing the behavior of the equalizer.
