Abstract  Abstract

In an orthogonal frequency division multiplexing (OFDM) system a transmitter and/or a receiver transmits separated data stream in a non-orthogonal spatial channel. Each of the spatial channels can share a same OFDM sub-carrier and can utilize the multi-path characteristics s of a spatial channel and allow transmission of extra data without increasing bandwidth. A space frequency sub-carrier modulation assignment can be dynamically distributed by taking each sub-carrier as the basis or distributed dynamically by taking each spatial channel as the basis in order to help the data carrying capability of a maximal channel. In some embodiment solution each of the spatial channels can be associated with one of the space diversity antennas. In other embodiment solution wave beam formation can be performed in order to allow signal transmission and/or receiving in spatial channels.
