WebAbstract. While the carrier frequency offset is a phenomenon that occurs due to frequency mismatch at the receiver, high peak-to-average power ratio occurs at the transmitter due to summation of multiple sinusoids. Occasionally, these sinusoids can add coherently to yield a very high amplitude compared to the average amplitude, resulting in a ...
