ABSTRACT:
A transmitter broadcasts a signal having a different code characteristic for each of several directions. A receiver receives the broadcast signal from one of the directions and generates an expected signal for that direction based on the code characteristic for that direction. The receiver detects the broadcast signal from the direction based on the expected signal for that direction.
