Method and system for dynamic channel assignment and assignment of pilot channel in mimo-ofdm/ sdm system

The present invention is a multi-received from the orthogonal frequency division multiplexing mobile communication system using a plurality of frequency sub-channel transmits data, to the mobile terminal by the base station with multiple receive antenna having multiple transmit antennas the multiple transmit antennas in order to assign the spatial channels to the antennas, selecting a mobile station having the maximum communication capacity of the corresponding plurality of spatial channels and the mobile terminal to each of the plurality of frequency sub-channels, wherein the selected mobile station by performing a first process of allocating one of a plurality of spatial channels, and performing the first process repeated until the mobile station to be selected both in sequence and assigning the plurality of spatial channels to the mobile station, It is one of a moving the plurality of spatial channels are assigned to the terminal having the maximum communication capacity Performs a second step of replacing the mobile terminal, and performing the second process repeated for the other mobile terminals except the mobile terminal is replaced in the mobile terminal until the communication capacity are not increased. OFDM, MIMO, SDM, a subchannel, a spatial channel is assigned, pilot matrix, the communication capacity
