摘要： An apparatus and method for receiving signals in a multiple-input, multiple-output (MIMO) wireless communication system is provided. A receiving end using as many as N Receive (Rx) antennas includes a first detector, as many as (N−2) nth detectors, and an Nth detector. A signal detection technique of the present invention has a low complexity and a throughput similar to that of a Maximum Likelihood (ML) scheme in a Multiple-Input Multiple-Output (MIMO) wireless communication system using a Spatial Multiplexing (SM) scheme.

摘要： A method and an apparatus for detecting a signal in a multi-antenna system using a spatial multiplexing are provided. The apparatus includes at least one antenna for receiving a signal, a channel estimator for estimating a channel using the received signal, a detector for calculating multiplication values commonly used to determine a Euclidean distance using the receive signal and channel information and for detecting a transmitted signal by calculating Euclidean distances of one or more candidate symbols using the receive signal and the determined multiplication values and a decoder for demodulating and decoding the detected signal. Hence, the computational complexity of the signal detection can be mitigated.
