Abstract
Aspects of the subject disclosure may include, for example, receiving an RF signal having a carrier wave component operating at a carrier frequency within a millimeter wave spectrum and an information component based on a phase modulation of the carrier wave component. The received RF signal is divided into first and second signal portions that remain in phase with respect to each other. The first signal portion is delayed by one symbol period of the phase modulation and combined with the second signal portion to obtain a combined output signal. An in-phase portion of the combined output signal is detected via a non-linear energy detector, wherein an amplitude of the first detected signal corresponds to the in-phase portion of the received RF signal. The first combined output signal includes information of the information component. Other embodiments are disclosed.
