TIME ERROR COMPENSATION ARRANGEMENT AND MULTI-CARRIER MODEM COMPRISING THE ARRANGEMENT

摘要

A time error compensation arrangement (TCOMP) that compensates for a time error (.epsilon., .DELTA.k) between a transmitter sample clock in a multicarrier transmitter and a receiver sample clock (CLK) in a multi-carrier receiver (RX1, RX2) includes a digital time correction filter (FILTER, FILTER'), operative in time domain, to compensate for a linearly increasing contribution (.DELTA.k) in the time error (.epsilon., .DELTA.k) and rotation means (ROTOR), operative in frequency domain, to compensate for a second, remaining contribution (.epsilon.) in said time error (.epsilon., .DELTA.k).
