ABSTRACT:
A base station that communicates with subscriber stations in an OFDM wireless network. The base station transmits a first data stream and a second data stream to a subscriber station using a first virtual antenna and a second virtual antenna. The base station allocates first data symbols associated with the first data stream to be transmitted from the first virtual antenna in a first selected group of subbands of OFDM subcarriers and allocates second data symbols associated with the first data stream to be transmitted from the second virtual antenna in a second selected group of subbands of OFDM subcarriers.
