A COMMUNICATION SYSTEM FOR TRANSMITTING AND DEMODULATING A COMMUNICATION SIGNAL USING AN ADAPTIVE ANTENNA ARRAY
摘要:
In a transceiver for transmitting a communication signal from an antenna array (302) in a wireless communication system, a different element pilot is transmitted from a plurality of antenna elements in an antenna array. Thereafter, transmitter control data based upon measured characteristics of the element pilots as measured at a subscriber unit is received at the transceiver (308). In response to the transmitter control data, a plurality of adaptive array weights for modifying a plurality of element communication signals are determined (306). Next, the transceiver determines that the subscriber unit is ready to receive a communication signal transmitted from the antenna array (312) and weighted according to the plurality of adaptive array weights (306). In response to determining that the subscriber unit is ready, the transceiver modifies the plurality of element communication signals according to the determined plurality of adaptive array weights.
