摘要： A receiving apparatus and a receiving method for interference cancellation in a wireless communication system are provided. The receiving apparatus includes a detector for estimating a desired signal and an interference signal by Multiple Input Multiple Output (MIMO)-detecting received signals; a first decoder for iteratively decoding the interference signal output from the detector; a second decoder for iteratively decoding the desired signal output from the decoder; and an LLR updater for updating an interval LLR value of the second decoder using an interval LLR value of the first decoder. Since the SIC/PIC is applied in the process of the iterative decoding of the decoder, the latency can be eliminated by applying the SIC/PIC after the completion of the decoding.

In a method for operating a Base Station (BS) in a MIMO wireless communication system, a reference signal including pilot signals, which are divided by a predefined number of bands and are multiplied by respective codes in a codebook, is transmitted. One or more Mobile Stations (MSs) destined for spatial multiple access are selected using an index of a band and CQI of the band corresponding to the index, which are fed back from one or more MSs. A precoding matrix is generated to process data streams of the selected one or more MSs.
