Abstract
In a multi-user radio receiver, a method and apparatus for reducing the effects of non-linear distortion due to adjacent channel interference (ACI) includes receiving and processing a multi-user information signal to provide a plurality of multi-user information values and then detecting, from the plurality of multi-user information values, at least a first information value having a signal strength which is relatively high compared with the signal strengths of the other plurality of multi-user information values. The apparatus then utilizes the plurality of multi-user information values, the first information value and a spectral representation of the first information value to generate a plurality of second information values having significantly reduced adjacent channel interference with respect to the first information value. The method and apparatus can thus increase the system capacity by increasing the frequency reuse factor in the a receiver system (e.g. a wideband receiver system) for wireless LAN applications.
