Abstract
System and methodologies for amplifier gain control in a communication system are provided herein. By leveraging similarities between the distribution of received signal samples in an MB-OFDM system and a Gaussian distribution, various algorithms described herein can be utilized to perform fast and low-complexity amplifier gain tuning. Received signal strength indication information corresponding to analog signal samples and/or digital signal samples obtained from an analog to digital converter are analyzed to obtain a signal energy distribution. The obtained signal energy distribution is then compared to a reference Gaussian distribution to adaptively tune an associated amplifier gain.
