Abstract
Blind channel impulse response combining for noise mitigation in channel estimation in a TD-SCDMA receiver includes applying a correlation function to pairs of channel impulse response windows associated with non-desired user equipments, grouping all those channel impulse response windows having a correlation function above a predetermined threshold as identified with the same user equipment, and combining the channel estimation results from each identified user equipment in the group to mitigate noise.
