Abstract
A method and apparatus for implementing transmit and receive beamforming in an orthogonal frequency division modulation (OFDM) multiple-in multiple-out (MIMO) system. The OFDM MIMO system includes at least one transmitter and at least one receiver. A receive information vector is determined based upon channel estimates performed at the transmitter and the receiver.

A method for transmit and receive beamforming in an orthogonal frequency division modulation (OFDM) multiple-in multiple-out (MIMO) system comprising at least one transmitter and at least one receiver, the method comprising:
- performing a channel estimate at the transmitter;
- performing a channel estimate at the receiver;
- and
- determining a receive information vector based upon the channel estimates performed at the transmitter and the receiver.
In an orthogonal frequency division modulation (OFDM) multiple-in multiple-out (MIMO) system comprising a plurality of wireless transmit/receive units (WTRUs), each WTRU comprising:
- a receiver;
- a transmitter;
- and
- a processor in communication with the receiver and the transmitter, the processor configured to perform a transmit channel estimate on a signal transmitted by the transmitter, perform a receive channel estimate on a signal received by the receiver, and determine a received information vector based upon the transmit and receive channel estimates.
In an orthogonal frequency division modulation (OFDM) multiple-in multiple-out (MIMO) system comprising a plurality of wireless transmit/receive units (WTRUs), each WTRU including an integrated circuit (IC), the IC comprising:
- a receiver;
- a transmitter;
- and
- a processor in communication with the receiver and the transmitter, the processor configured to perform a transmit channel estimate on a signal transmitted by the transmitter, perform a receive channel estimate on a signal received by the receiver, and determine a received information vector based upon the transmit and receive channel estimates.
