摘要： A method for assigning a single frequency sub-channel to a plurality of MSs (Mobile Stations) in an OFDM (Orthogonal Frequency Division Multiplexing) system utilizing SDM (Spatial Division Multiplexing) with multiple transmit/receive antennas. In the method, a BS (Base Station) can effectively assign a pilot channel to estimate a downlink channel. The BS divides the single frequency sub-channel into a plurality of spatial channels, and sequentially assigns the plurality of spatial channels to the MSs having the maximum communication capacity, thereby transmitting signals of the MSs through the single frequency sub-channel.

摘要： A signal detection method and apparatus in a receiver in a MIMO mobile communication system. The receiver orders symbol combinations transmittable from a transmitter in an ascending order of the difference between the symbol combinations and transmit symbols produced by eliminating inter-symbol interference from a received signal, initializes a symbol combination with the minimum difference to an ML solution, calculates the distance between a first symbol combination and the transmit symbols and the cost of a second symbol combination, detects a symbol combination having a distance to the transmit symbols equal to the distance between the first symbol combination and the transmit symbols, and having a minimum distance, and decides the first symbol combination as the ML solution if the minimum distance exceeds the distance between the first symbol combination and the transmit symbols.
