Abstract:
1. A system for providing gain control to a gain stage of a wireless communication system that receives a radio frequency (RF) signal, wherein the RF signal includes a plurality of sub-frames, the system comprising: a gain control module that determines a received signal strength indication (RSSI) value and a decibel amplitude level relative to full scale (dBFS) value of a first sub-frame of the plurality of sub-frames, and stores a first gain value for a second sub-frame of the plurality of sub-frames when configured to operate in an automatic gain control (AGC) mode and a second gain value for the second sub-frame when configured to operate in a manual gain control (MGC) mode, wherein the second sub-frame is received subsequent to the first sub-frame; and a mode selection module, connected to the gain control module, that: wherein the gain stage amplifies the portion of the RF signal corresponding to the second sub-frame based on the first gain value when the gain control module operates in the AGC mode and the second gain value when the gain control module operates in the MGC mode.
