Smart antenna systems have recently played a central role in removing narrowband multiple-access interference (MAI) in wireless communications. However, if these adaptive systems are proposed for wideband wireless communications the addition of some form of frequency compensation is required. The frequency compensation methods which have been examined are the spectral decomposition, focussing and interpolating techniques. Their performances are compared on the basis of the resulting array patterns. The three frequency compensation techniques are combined with the constant modulus algorithm (CMA) for the adjustment of adaptation weights. Simulation results showing the performance of the system with and without compensation are given and discussed
