A method of compensating for loss of orthogonality in beam transmission in a wireless communications network to improve signal downlink performance. The method includes the determination of two or more transmission directions for transmitting signal beams to a destination. Once transmission directions are determined, time delays associated with transmitting a beam along each determined direction are calculated and a reference direction is obtained as the direction corresponding to a maximum of the calculated delays. Each transmitted signal is delayed by the proper time delay so that multiple beams transmitted to the destination are simultaneously received at the destination. |
