Abstract:
A method for controlling a signal transmission power, comprising the steps of:(a) demodulating a received signal to produce a demodulated signal;(b) distorting said demodulated signal to produce a distorted demodulated signal;(c) determining a signal quality measurement based on said distorted demodulated signal which represents a value directly proportional to signal quality;(d) requesting an adjustment in the transmission power based on said signal quality measurement comprising:(i) comparing said determined signal quality measurement to a preselected threshold value; and(ii) requesting an increase in transmission power if said signal quality measurement exceeds said threshold;(e) decoding said demodulated signal to produce decision data;(f) decoding said distorted demodulated signal to produce distorted decision data;(g) determining a second signal quality measurement based on said distorted decision data; and(h) adjusting said threshold based on said second signal quality measurement.
