Abstract
The present invention discloses a transmitter, a receiver, and a method for receiving and transmitting a radio frequency signal, and relates to the field of radio communications technologies, which can perform carrier recovery and generation at a front end of a radio frequency circuit, thereby reducing a running cost of a baseband chip. The method includes: generating, by an amplitude discriminator/phase detector according to an intermediate-frequency analog signal, a signal amplitude pulse signal/signal phase pulse signal that is not corrected; generating, by a bit error matrix corrector, an amplitude/phase correction control signal; correcting, by the amplitude discriminator/phase detector, the signal amplitude pulse signal/signal phase pulse signal according to the amplitude/phase correction control signal; and converting, by an amplitude code generator/phase code generator, a corrected pulse signal into a corresponding digital code. The present invention is applicable to receiving/transmitting a radio frequency signal.
