  • Communications adaptive automatic gain controller
    Patent number: 7970084
    Abstract: An adaptive scaling processor operates in combination with a conventional automatic gain control controller providing an amplification gain A to m-ary symbol-modulated communication signals, the scaling processor scaling by a scaling factor Z the m-ary communication signal for providing an over all gain of an (A)(Z) product minimizing the BER that is optimum for the communications channel for improved BER performance in communication systems.
