The system (10) includes a transmitter (14) for generating a signal in the time domain and transforming the signal to the frequency domain, wherein the transmitter (14) suppresses a plurality of sub-carriers of the signal, The resulting truncated signal is transmitted to the receiver (18) through a noisy channel (16). The receiver (18) receives a noisy signal and recovers the carrier signal and, hence, the partial response signal from the noisy signal. The method includes selecting a cyclic convolver (24) having predefined values, applying the cyclic convolver (24) to a signal to produce a partial response signal, dropping a plurality of sub-carriers of the partial response signal, to generate a modulated carrier signal that is ready for transmission. |
