ABSTRACT:
A communication system comprising transmitting circuitry arranged to transmit a data signal and a timing signal; and receiving circuitry arranged to receive the data signal and the timing signal. The receiving circuitry comprises a first finite impulse response filter arranged to generate a filtered timing signal dependent on the timing signal and a at least one mixer signal; a decision feedback circuit arranged to generate the at least one mixer signal dependent on the filtered timing signal and a calibration signal; and a second finite impulse response filter arranged to generate a filtered data signal dependent on the data signal and the at least one mixer signal.
