<P>PROBLEM TO BE SOLVED: To provide a method for achieving transmit and/or receive diversity using multiple antennas. <P>SOLUTION: A single transmitter chain within a wireless terminal is coupled over time to a plurality of transmit antennas 312. At any given time, a controllable switching module 310 couples the single transmitter chain to one of the plurality of transmit antennas. Over time, the switching module couples the output signals from the single transmitter chain to different transmit antennas. Switching determinations are based upon predetermined information, dwell information, and/or channel condition feedback information. Switching is performed on some dwell and/or channel estimation boundaries. Each of multiple transmitter chains is coupled to a different transmit antenna. Information to be transmitted is mapped to a plurality of tones. <P>COPYRIGHT: (C)2013,JPO&INPIT |
