Abstract
The present disclosure provides a receiver and a signal processing method. The receiver includes: a first frequency mixer, performing frequency mixing on a received signal by using a square wave signal to obtain a first frequency-mixed signal; a first low-pass filter, filtering the first frequency-mixed signal to obtain a first filtered signal; a first analog-to-digital converter, performing analog-to-digital conversion on the first filtered signal to obtain a first sampled signal; and a signal processing unit, estimating, according to the first sampled signal, an information symbol transmitted by a transmit end, where the square wave signal is generated according to a carrier frequency estimation value of the received signal. The receiver according to embodiments of the present disclosure provides better flexibility.
