Frequency and timing offset compensation

Especially the present invention is applicable to the equipment and the module for correcting the error introduced into a radio signal after transmission of a radio signal about wireless communications. Signal processing -- or the received radio signal which is introduced by either by a transmitting medium -- it is not desirable -- the equalizer with which influence is compensated is offered. Working and an equalizer carry out the multiplication of the signal by which compound reception was carried out by the compound correction signal with which these influences are compensated. A tap correction signal corrects the channel influence (namely, channel strain) which carries out time change, and a timing tracking signal corrects a carrier frequency offsetting error, and a phase tracking signal corrects a sampling frequency offsetting error.
