1. A method comprising:

  • generating a channel codebook by identifying a subset of antenna configurations from a plurality of antenna configurations of an antenna associated with a transmitter by;

    transmitting a sequence of symbols from the transmitter to a receiver using the plurality of antenna configurations, wherein each antenna configuration provides a unique transmission characteristic to the receiver, and wherein the antenna configurations are generated by changing the propagation environment around the transmit antennas;

    receiving feedback from the receiver that identifies the subset of antenna configurations; and

    ,generating channel codebook entries corresponding to the subset of antenna configurations; and

    ,transmitting data from the transmitter to the receiver by using the channel codebook to select a sequence of antenna configurations from the subset of antenna configurations based on the data to be transmitted, and transmitting symbols using the selected sequence of antenna configurations.
