Abstract
A plurality of predetermined amplifier gain states for a low noise amplifier (LNA) are run during initial acquisition in a time division duplex (TDD) system. Acquisition of a received signal is determined based on searching across the plurality of predetermined amplifier gain states. Forcing the amplifier gain into a set of predetermined gain states affords quicker resolution of initial acquisition for setting the gain of the LNA, which in TDD systems is complicated due to an uncertain uplink/downlink timeline that precludes continuous operation of a gain setting algorithm run in the LNA.
