摘要
A multicarrier transceiver for communicating spatially multiplexed orthogonal frequency division multiplexed (OFDM) signals over two or more spatial channels in a wireless access network in accordance with an orthogonal frequency division multiple access technique with a plurality of antennas is generally disclosed herein. In some embodiments, the multicarrier transceiver comprises a matrix generator to generate a matrix for precoding transmission symbols based an indicator received from a receiving station, the indicator being based at least in part on channel characteristics. The multicarrier transceiver also includes a precoder to multiply the transmission symbols by the matrix for transmission on groups of subcarriers that comprise the OFDM signals using the antennas for transmission through two or more spatial channels, each of the two or more spatial channels to concurrently convey separate spatially multiplexed data streams over a same set of subcarriers.
