Abstract:
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. The method includes receiving a composite signal at the BTS antenna. The composite signal comprises a desired MS signal and an interfering MS signal. Thereafter, a known desired random sequence and a known interfering random sequence is applied to pilot symbols of the composite signal, resulting in a first de-randomized signal and a second de-randomized signal. Finally, the channel estimate is obtained by weighting and summing the first de-randomized signal and second de-randomized signal.
