Patent ID: 8068535

Claim:
A method, in a receiving equipment for demodulating received signals, the method comprising: performing a demodulation calculation, the performing further comprising iteratively calculating, in a plurality of successive iteration steps, coefficients or elements of a vector w to obtain a solution to a system of linear equations represented by a matrix equation Rw=h, wherein R is a matrix of known elements, h is a known vector, and the values of the coefficients or elements of the vector w are used by demodulating circuits in the receiving equipment to produce demodulated signals, and for each successive iteration step among the plurality of successive iteration steps, calculating a signal to interference plus noise ratio (SINR) for the received signals, after the received signals are demodulated using the values of the coefficients or elements of vector w calculated in each successive iteration step; and stopping the demodulation calculation using the SINR in a stopping condition or in a stopping algorithm.
