摘要:
A time error compensation arrangement (TCOMP) that compensates for a time error (&egr;, &Dgr;k) between a transmitter sample clock in a multi-carrier 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 (&Dgr;k) in the time error (&egr;, &Dgr;k) and rotation means (ROTOR), operative in frequency domain, to compensate for a second, remaining contribution (&egr;) in said time error (&egr;, &Dgr;k).
