Claim:
1. A method comprising: at a transceiver of a base station, generating a first set of estimated symbols based on the received combined uplink signal and the first location-specific signature waveform associated with the first terminal device, in which the first location-specific signature waveform is determined based on the first probe signal sent from the first device, the first set of estimated symbols representing a rough estimate of the symbols sent from the first device; generating a second set of estimated symbols based on the received combined uplink signal and the second location-specific signature waveform associated with the second device, in which the second location-specific signature waveform is determined based on the second probe signal sent from the second device, the second set of estimated symbols representing a rough estimate of the symbols sent from the second device; determining interference based on at least one of the first set of estimated symbols or the second set of estimated symbols; and generating a refined first set of estimated symbols by canceling the interference from the first set of estimated symbols, the refined first set of estimated symbols representing a refined estimate of the symbols sent from the first device.
