AN IMPROVED METHOD FOR ESTIMATING ADAPTIVE ARRAY WEIGHTS IN A WIRELESS COMMUNICATION SYSTEM |
摘要 |
A transmitter (300) uses adaptive array weights to modify a gain and a phase of a communication signal (TCH1) to produce a plurality of element communication signals coupled to antenna elements (1...n) in an adaptive array antenna (302). The communication signal is transmitted along with an element pilot signal (P1...Pn) that is coupled to one of the elements in the adaptive array antenna (302). In a receiver, the communication signal is received, and the element pilot signal is received. Thereafter, the adaptive array weights used at the transmitter (300) are estimated in response to comparing characteristics of the received element pilot signal (P1...Pn) to characteristics of the received communication signal.
