Abstract:
An apparatus includes a radio frequency (RF) receiver, which includes a digital signal arrival (DSA) detector to detect arrival of a transmitted signal. The DSA detector includes a frequency discriminator to receive a signal derived from a received RF signal to generate a first complex signal. The DSA detector further includes a correlator coupled to receive and process the first complex signal and to generate a second complex signal. The DSA detector in addition includes a Coordinate Rotation Digital Computer (Cordic) circuit to receive and process the second complex signal to generate a phase signal and a magnitude signal.
