Abstract: An apparatus includes a radio frequency (RF) receiver, which includes a differentiator to differentiate a phase signal to generate a differentiated signal. The RF receiver further includes a correlator coupled to receive and correlate the differentiated signal, and a memory to receive and store the differentiated signal. Samples of the differentiated signal are provided to the correlator and to the memory synchronously.

Abstract: A receiver includes an analog receiver and a digital processor. The analog receiver has an input for receiving a radio frequency (RF) signal, and an output for providing a digital intermediate frequency signal. The digital processor has an input for receiving the digital intermediate frequency signal, and an output for providing digital symbols. The digital processor measures peak-to-peak frequency deviation of the digital intermediate frequency signal, and performs a digital signal processing function on the digital intermediate frequency signal to provide the digital symbols based on the peak-to-peak frequency deviation so measured.
