Abstract
A communication receiver which applies signal processing for quantitatively estimating receive signal factors such as communication channel quality, signal characteristics, and overall system received bit error rate (BER) or packet error rate (PER) and which applies a general algorithm for mapping these estimated factors to control receiver performance and minimize power consumption.
Claims16
A system for power control, the system comprising:
- a detector operable to generate a signal strength indication according to one or more signals from a receiver, wherein the detector is operable to estimate a Doppler frequency according to the one or more signals from the receiver;
- an estimator operable to estimate a frequency and an amplitude of an interferer according to the signal strength indication;
- and
- a controller operable to generate one or more control signals according to one or both of the frequency and the amplitude of the interferer, wherein the one or more control signals adjust power consumption in the receiver, and how frequently the one or more control signals are updated is based on said estimated Doppler frequency.
