Abstract  Abstract

The invention claims a transmitter and/or receiver transmit separate data streams in non-orthogonal spatial channels orthogonal frequency division multiplexing (OFDM) system . Each spatial channel may use the same set of OFDM subcarriers and can use the multipath characteristics of the spatial channels allows transmitting additional data without an increase in frequency bandwidth. spatial frequency subcarrier modulation assignments may be based on each sub-carrier dynamically allocation can also be based on dynamically assigned to each spatial channel to help maximize channel data carrying capacity. In some embodiments each spatial channel can be connected with one of a plurality of spatially diverse antennas is associated. In other embodiments can perform beamforming to allow transmitting and/or receiving signals in the spatial channel.
