Patent ID: 8098631

Claim:
A method comprising the steps of: i) initializing with channel matrix estimates and inner codes of all co-channel transmitter sources in a wireless network, modulation and coding schemes of other transmitter sources in said wireless network; ii) converting each channel matrix estimate into an effective channel matrix responsive to the inner code of the corresponding transmitter source; iii) selecting iteratively from a first set of transmitter sources in said wireless network transmitting at fixed rates, a transmitter source which maximizes a first metric; iv) computing iteratively a filter for the transmitter source which maximizes the first metric; v) selecting iteratively from a second set of transmitter sources in said wireless network, a transmitter source which maximizes a second metric; vi) computing iteratively a rate and a second filter for the transmitter source which maximizes the second metric; and vii) obtaining an ordered set of indices of all transmitter sources that will be decoded along with their corresponding filters, and feedback rates for all transmitter sources of interest; wherein the step of computing the filter for the transmitter source which maximizes the first metric and the step of computing the filter for the transmitter source which maximizes the second metric are responsive to a particular structure of a covariance matrix of the noise and signals from remaining sources and employs the properties of 8×8 sub-matrices of said covariance matrix in order to efficiently compute its inverse.
