AUTOMATIC GAIN CONTROL FOR TIME DIVISION DUPLEX LTE

摘要

Data samples of a signal transmitted by a WWAN are captured during a first set of capture ticks for a first capture period defined by a plurality of contiguous ticks. The first set of capture ticks comprises a first subset of the plurality of contiguous ticks, and the capturing is done using a WLAN receive chain having a switchable LNA gain state. The capturing of data samples is repeated for at least one additional capture period defined by a plurality of contiguous ticks to capture data samples during at least one additional set of capture ticks comprising an additional subset of the plurality of contiguous ticks for which data samples were not previously captured. The LNA gain state of the WLAN receive chain is switched at least once over the plurality of capture periods. Gain state switching may occur a capture period, or between capture periods.

1. A method of capturing a plurality of data samples over a plurality of capture periods to form continuous data including a signal of interest periodically transmitted by a wireless wide area network (WWAN), said method comprising:
for a first capture period defined by a plurality of contiguous ticks, capturing data samples during a first set of capture ticks, wherein:
the first set of capture ticks comprises a first subset of the plurality of contiguous ticks, andthe capturing is done using a wireless local area network (WLAN) receive chain having a switchable LNA gain state; and repeating the capturing for at least one additional capture period defined by a plurality of contiguous ticks in order to capture data samples during at least one additional set of capture ticks comprising an additional subset of the plurality of contiguous ticks for which data samples were not previously captured, wherein the LNA gain state is switched at least once over the plurality of capture periods.
