ABSTRACT:
MIMO modulation is supported in a wireless network with at least one degenerate node. A transmitter separates data into multiple streams for modulation. To transmit the modulated data, the transmitter uses a separate antenna for each data stream or coherently combines the modulated data streams prior to transmission via fewer antenna than modulated data streams. In either case, the received signal includes a contribution from each data stream. A receiver is configured for processing multiple signals sent in parallel from multiple transmit antennas; thus, the operation of the receiver is unaffected by whether the multiple data streams of the transmitter were combined in the channel after transmission or in whole or part in the transmitter prior to transmission.
