Patent ID: 8817864

Claim:
A communication device comprising: a plurality of paths that are provided in the device and transmit signals; a storage that stores, for each signal unit, information on a path and information on other path(s) that causes crosstalk in a signal on the path that are associated with each other; an adjuster that adjusts transmission characteristics to be a favorable state by adjustment of the waveform of the signals on the paths; and a controller that gathers the information stored in the storage for each signal unit; identifies, among the paths and based on the gathered information, a combination of paths of which transmission characteristics are adjustable at the same time, identifies the total number of adjustments for all paths and the order of the adjustments based on the combination, controls the adjustments of the transmission characteristics of the paths by the adjuster to be performed in the identified order, and controls suppression of crosstalk due to the other path(s).
