ABSTRACT:
The disclosed technology relates to a communication system and method in which multiple versions of a signal are processed to detect the signal. The communication system can include transmitters that communicate different versions of a signal to a receiver. The different versions are weighted versions of the signal and are communicated on different channels. The weight for a weighted signal is based on an inverse of an estimate of the phase shift of the particular channel to which the weighted signal will be communicated. The weights are also based on a unity gain such that each weighted signal has the same magnitude as the original signal. A receiver that receives the weighted signals processes the received signals to detect the original signal.
