METHOD FOR SEARCHING PILOT SIGNALS TO SYNCHRONIZE A CDMA RECEIVER WITH AN ASSOCIATED TRANSMITTER
Abstract:
A method for synchronizing a CDMA receiver (201) to a transmitter when an adaptive antenna is utilized to receive transmitted data, wherein a receiving antenna system is adapted between a 360 DEG reception angle pattern (i.e., an omni-directional pattern) and a fixed reception angle (i.e., a directional pattern) by permitting the receiver to identify a pilot signal having the largest magnitude. The receiver minimizes interference from other pilot signals by steering antenna pattern nulls toward other transmitters. As a result, the time required for the receiver (201) to acquire a valid pilot signal is significantly reduced.
