Diversity for direct sequence spread spectrum wireless communication systems is provided in a receiver having M antennas (T1,T2). Distinct weighting signals (W1 (t), W2 (t)) are applied to information signals received at each of the M antennas, with the weighting signals being, for example, distinct changes in either phase or amplitude. Applying weighting signals to each of the information signals received at the M receiver antennas results in constructive addition (18) of derived signal vectors at predetermined intervals, which eliminates deep fading at the receiver. <IMAGE> |
