Claim:
1. A method of link optimization in a multi-user communications network having a plurality of transmitter-receiver communications links that are mutually interfering, the method comprising: initializing a forward-link signal communication model that represents transmit characteristics of a plurality of forward-link transmitters of the communications network; computing an initial solution to an optimization problem having at least one power constraint corresponding to the transmitters as a function of the initialized forward-link signal communication model; and converging on an optimal solution to the optimization problem by iterating, until an updated solution to the optimization problem satisfies a predetermined convergence criterion, steps comprising: computing a forward-link interference model as a function of the forward-link signal communication model; updating a reverse-link signal communication model according to the forward-link interference model; computing a reverse-link interference model as a function of the updated reverse-link signal communication model; updating the forward-link signal communication model according to the reverse-link interference model; normalizing the updated forward-link signal communication model to fit the at least one power constraint; and computing the updated solution to the optimization problem as a function of the normalized updated forward-link signal communication model.
