ABSTRACT:
A communication system for coordinated downstream diversity transmission includes a central processing center for selecting adaptive transmitter parameters and adaptive receiver parameters to as to optimize an estimate of a transmitted data symbol received by a given mobile unit while constraining power output as well as accounting for interference to other mobile units within the propagation range of base units controlled by the central processing center. The adaptive transmitter and receiver parameters are determined from the solution of an eigenvalue formulation expressed in terms of the transmission path characteristics between the mobile unit and the base unit as well as transmission signal sources and mobile unit processing filters.
