摘要： A communication system based upon frequency-domain MIMO processing is disclosed. A transmitting device (20) of the communication system transforms time-domain signals (S1-3 [M]) into frequency-domain signals (S1-3 [K]) , and weights (22) each frequency-domain signal to form weighted frequency-domain signals (X1-3 [K]) with each weighted frequency-domain signal (X1-3 [K]) being a function of each frequency-domain signal. The transmitting device (20) transmits weighted time-domain waveforms as a function of the weighted frequency-domain signals (X1-3 [K]) . In response thereto, a receiving device of the communication system provides frequency-domain samples that are a function of the one or more weighted time-domain waveforms and weights each frequency-domain sample to form one or more weighted frequency-domain samples with each weighted frequency-domain sample being a function of each frequency-domain sample. The receiving device decodes the weighted frequency-domain sample to obtain the information represented by the time-domain signals.

摘要： A method and apparatus for performing stream weighting in a spatial-division multiple access communication system is provided herein. During operation the base station receiver receives channel information from mobiles (also known as users or nodes) and calculates transmit antenna weights that maximize the power delivered to each mobile while allowing for a small amount of crosstalk to exist between users. Information or data is transmitted to the nodes utilizing the appropriate stream weights. By allowing tolerable amounts of cross talk, the coherent gain to the desired SDMA user can be increased, and thus the overall performance is improved.
