Abstract

A multicarrier transmitter comprising: a modulator for each of a plurality of data streams to generate a set of constellation symbols for each of a plurality of frequency subchannels based on a number of subcarriers associated with each subchannel; and subcarrier mapping circutry for each of a plurality of spatial channels to assign the sets of the constellation symbols to the subcarriers of each subchannel, wherein the subcarrier mapping circuitry is to change assignments among the subcarriers of some spatial channels so that corresponding subchannels use different sets of subcarriers on some spatial channels.
