A system for detecting the level of the noise floor due to circuit noise as seen at the ADC for a wireless receiver. The system measures power after digitizing and filtering, and subtracts off any variable gain used in the analog front end to determine differentially the size of the signal at the antenna....http://www.google.fr/patents/US7245893?utm_source=gb-gplus-shareBrevet US7245893 - Method and system for noise floor calibration and receive signal strength detection
