Partial response signaling for orthogonal frequency division multiplexing

System (10) comprises for generating signal and a circular prefix transmission (14), a transmitter (14) for restraining the signal of sub-marks, generating partial response signal. Obliterates the partial response signal a part, and used detruncation signal demodulate intelligent signal for obtaining. The intelligent signal processing with noise channel (16) is transmitted to a receiver (18). The receiver (18) and a noise signal, and quick-recovery the intelligent signal, therefore from with a noise signal recovering the partial response signal. The method comprises the preset value constant convolver comprising a selecting (24); (24) applied to the circulation convolver the signal, generating partial response signal, obliterates the partial response signal of sub-marks, wherein the front detruncation capacity circular prefix of rubber response signal, and conversion detruncation the partial response signal and circular prefix, to generate a time-based signal; the signal is used for generating an intelligent signal of,) is provided with a transmission.
