Dynamic gain for DAC illumination control

摘要: A transmitting device may control digital-to-analog converter (DAC) illumination to optimize signal noise ratio of a transmission signal. DAC be adjusted based, at least in part, on analog gain and estimated total transmit power particular For each destination, based tone map, amplitude back-off settings, or other characteristics. The is used determine an appropriate gain. Once are known, fine SNR achieved by adjusting level the digital domain. setting scale baseband prior operation. allows operate optimized within range DAC.
