Abstract
A multicarrier transmitter assigns for each of a plurality of spatial channels, sets of the constellation symbols to subcarriers of each subchannel. Constellation symbol assignments to the subchannels are circularly rotated among some of the spatial channels so that subchannels use different sets of subcarriers for each spatial channel for enhanced frequency diversity.
