Patent ID: 7916774

Claim:
A method of estimating a channel between a desired Mobile Station (MS) and a Base Transceiver Station (BTS) antenna of a one of a plurality of sectors of a BTS, comprising: the BTS receiving a composite signal, the composite signal comprising a desired MS signal and an interfering MS signal, wherein the desired MS signal is modulated by a first Pseudo Random Binary Sequences (PRBS) and the interfering MS signal is modulated by a second PRBS, and wherein the known desired random sequence comprises the first PRBS and the known interfering random sequence comprises the second PRBS; generating a first de-randomized signal, comprising multiplying a known desired random sequence by pilot symbols of the composite symbol; generating a second de-randomized signal, comprising multiplying a known interfering random sequence by pilot symbols of the composite symbol; the BTS estimating the channel by weighting and summing the first de-randomized signal and second de-randomized signal, comprising determining sums and differences of the first de-randomized signal and the second de-randomized signal, weighting the sums and weighting the differences with predetermined weights, and averaging the weighted sums and weighted differences, wherein the weighting for the sums and the weighting for the differences with predetermined weights comprises determining a PRBS characteristic value corresponding to the first PRBS and the second PRBS.
