<p>Spatial power allocation and bit loading of a MIMO System are performed based on pre-determined, expected values of spatial channel gains and SNRs of the spatial channels (correspond to different antennas). The expected values of spatial channel gains are calculated (64) based on a selected channel model (62). The SNRs of the spatial channels are then calculated based on water filling power allocation (66). Thus, no feedback information from the receiver about the spatial channels is necessary.</p> |
