Abstract
Improved receiver automatic gain control for OFDM-based communication systems is provided, thus realizing the full potential of OFDM systems to handle rapid variation in channel characteristics. The improved automatic gain control technique can also accommodate reception of multiple OFDM signals having disparate power levels via the same analog receiver chain and analog to digital converter while minimizing the arithmetic precision necessary for optimal digital processing. By reducing the necessary arithmetic precision, the cost of implementing the receiver with integrated circuit technology is greatly reduced.
