AUTOMATIC GAIN CONTROL FOR TIME DIVISION DUPLEX LTE

摘要

A plurality of data samples are captured during a single capture period using a WLAN receive chain, wherein the data samples include a signal of interest periodically transmitted by a WWAN. A preferred LNA gain state is selected from among a plurality of available LNA gain states for the WLAN receive chain. The plurality of gain states may be a discrete set of LNA gain states or may be a set of LNA gain states derived from energy measurements. The LNA gain state of the WLAN receive chain is set to the selected LNA gain state and data samples are captured during each of a plurality of contiguous capture ticks within a capture period. The captured data samples are processed to detect for the signal of interest.
