Abstract:
1. A method for initial acquisition in a communication system comprising: running a plurality of predetermined amplifier gain states for at least one amplifier in a predefined order during initial acquisition in a time division duplex (TDD) system having first and second antennas that each duplexes downlink and uplink signals for communication with a same communication station according to a TDD format; and determining initial acquisition from received signals based on searching across the plurality of predetermined amplifier gain states run in the predefined order until a known signal is detected; wherein, to support the initial acquisition, said running includes running a first gain state for a first signal, received via a first amplifier and the first antenna, simultaneously with running at least a second gain state for a second signal received via a second amplifier and the second antenna.
