Abstract
Transmission equipment that can be used up to a high frequency and simplifies a circuit design includes a THP preceding means on a transmitting side, and an equalizer means, wherein analog processing is carried out on a receiving side. Compensation of the frequency characteristic of a transmission channel is divided into the THP preceding means on the transmitting side and the equalizer means, so that due to compensation by the equalizer circuit, the absolute value of a THP coefficient becomes small, and a DAC with lower resolution, wherein stability of a loop of the THP increases, can be used. Detailed adjustment for adapting to the characteristic of a transmission channel is carried out by the THP, so that the equalizer circuit is only required to roughly compensate, and is not required to adjust. As a result, the equalizer circuit can be of a simple design.
