Abstract
A method utilizing intentionally generated in-band frequency harmonics to compensate for frequency error and frequency drift in a voltage controlled oscillator of a receiver, thereby eliminating the frequency synthesizer and RF divider required in conventional designs. The method includes modulating the intentionally generated frequency in a predetermined manner so that a receiver can identify the intentionally generated frequency and includes the use of plural frequency harmonics for use in a curve fitting technique to correct frequency error in the voltage controlled oscillator.
