Abstract:
A method of controlling signal gain in a receiver processing system for a received signal, the method comprising the steps of:amplifying the received signal by setting the signal gain to a maximum level during a gain adjustment sequence of the processing system;providing the amplified received signal to an analog-to-digital converter (ADC) that produces a predetermined number of ADC signal sample values in a single cycle of an estimated signal frequency of the received signal;determining the number of ADC signal sample values that indicate full scale magnitude of the received signal within a signal cycle; andadjusting the signal gain from the maximum level that causes the number of ADC signal sample values that indicate full scale magnitude to be above a predetermined saturation threshold so as to reduce the signal gain until the saturation threshold is not exceeded.
