Abstract
Systems and methods of convergence beamforming are disclosed. One method embodiment, among others, comprises receiving N data streams from at least N+1 antennas, where N is an integer greater than 1; determining signal characteristics of each received data stream; and adjusting the signal characteristics of N data streams to be transmitted based on the determined signal characteristics of the received N data streams. The convergence beamforming may be achieved by the orthogonalization of received multipath channel vectors. The transmission signals from a station are adjusted corresponding to the channel characteristics of the signals received by that station.
Claims21
A method, comprising:
- receiving a plurality of data streams at a plurality of receive antennas associated with a transceiver, wherein the plurality of data streams comprise a first data stream and a second data stream;
- determining at the transceiver first and second receive vectors comprising signal characteristics based on a plurality of received signals associated with the first and second data streams;
- determining a first transmit vector based on the first receive vector;
- determining a second transmit vector based on the first transmit vector and second receive vector;
- mapping at the transceiver a first transmit data stream across a plurality of transmit antennas based on the first transmit vector;
- and
- mapping at the transceiver a second transmit data stream across the plurality of transmit antennas based on the second transmit vector.
A transceiver, comprising:
- means for receiving a plurality of data streams;
- means for determining first and second receive vectors comprising the signal characteristics of each received data stream based on a plurality of received signals associated with the received data stream;
- means for determining a first transmit vector based on the first receive vector;
- means for determining a second transmit vector based on the first transmit vector and second receive vector;
- means for mapping a first transmit data stream based on the first transmit vector;
- and
- means for mapping a second transmit data stream based on the second transmit vector.
