ABSTRACT:
A system, a receiver apparatus, a transmitter apparatus and a method for inter-user interference cancellation when simultaneous transmissions from two wireless users to the same base station are repeated using the same time-frequency resource. The percentage of interference cancellation is pre-set and phase shifts of the first and repeated transmitted symbols for each mobile user are determined in accordance with this pre-set percentage. The receiver uses a pre-determined technique for estimating the received symbols in accordance with the pre-set percentage and phase shifts.
