Abstract:
Methods, devices, and computer program products for antenna searching with antenna selection are disclosed. In one aspect, an apparatus operable in a wireless communication system includes a first receiver, a second receiver, and a processor. The first receiver receives a first signal including pilot signals from a first antenna. The second receiver receives a second signal including pilot signals from a second antenna. The processor, while a receive diversity is enabled, demodulates the first and second signals, determines whether a first condition is satisfied, and, in response to determining that the first condition is satisfied, searches for pilot signals via the second receiver and not the first receiver. The first condition is satisfied when a signal strength of the first signal does not exceed a first threshold and a signal strength of the second signal exceeds a second threshold.
