Abstract:
1. A method for canceling an interference of each of a plurality of received signals, comprising the steps of: (a) estimating a channel according to a first predetermined number of pilot-tones, the channel comprising a plurality of sub-carriers, each of the sub-carrier corresponding to one of the received signal; (b) deciding a decision order relating to the sub-carriers; (c) selecting a second predetermined number of the received signals as the first processing signals according to the decision order; (d) estimating an estimated value for each of the first processing signals; (e) deciding a decided value for each of the estimated values; (f) estimating the channel according to the pilot-tones and the estimated values; and (g) canceling the interference of each of the first processing signals according to the corresponding decided value and the corresponding sub-carrier.
