ABSTRACT:
A radio communication device, which transmits or receives a signal at a predetermined carrier frequency. The device includes a reference oscillator, which generates a clock frequency having a clock frequency error relative to a specified frequency thereof, a processor, which estimates the clock frequency error and parses the error to determine coarse and fine error correction components, at least one frequency synthesizer, which responsive to the clock frequency and to the coarse error correction component, generates a partially corrected frequency having a residual frequency error, which partially corrected frequency is applied to process the signal and baseband processing circuitry, which applies the fine error correction component to process the signal so as to correct the residual frequency error.
