Abstract
The present invention relates to a method for using the peak-to-average power ratio (PAR) of signals received by a receiver to control the gain of the receiver for an analogue-to-digital converter (ADC) and/or to control the dynamic range of the ADC.
Claims28
A method of processing a signal, comprising:
- determining average power of the signal;
- determining peak-to-average power ratio (PAR) of the signal;
- amplifying the signal based at least in part on the PAR in conjunction with the average power;
- and
- converting the amplified signal from analogue into digital.
