Abstract

Multichannel adaptive equalization combines the concepts of spatial diversity and temporal equalization to improve receiver performance in a line-of-sight communication environment. We derive the optimal Wiener filter for conditions common to this environment. We specifically analyze the effect of a CW interference on this solution and demonstrate the dependence of receiver performance on the multichannel adaptive equalizer (MAEQ) spatial-temporal beam pattern
