|20080310492||Parameter Adjustment Device and Parameter Adjustment Method - 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.||12-18-2008|
|20080281986||Parameter adjusting device - A parameter adjusting device optimizes parameters using a genetic algorithm by using a plurality of processing devices. The plurality of processing devices is respectively configured to individually and simultaneously execute the genetic algorithm and to, a predetermined period prior each local search, be such that each processing device, in accordance with the genetic algorithm processing, based on predetermined numbers, send individuals of a genetic population to others of the plurality of processing devices and further configured to have a migration arrangement for receiving the predetermined numbers.||11-13-2008|
