Frequency domain partial response signaling with high spectral efficiency and low peak to average power ratio

摘要

The system includes a transmitter for generating a signal in the time domain and transforming the signal to the frequency domain, wherein the transmitter suppresses a plurality of sub-carriers of the signal, The resulting truncated signal is transmitted to the receiver through a noisy channel. The receiver 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 having predefined values, applying the cyclic convolver 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.
