Abstract
The present invention relates to a link quality determination unit (LQ-DET) for determining a link quality (LQ) of a transmission link (TL) between an OFDM transmitter (TR) and an OFDM receiver (RC) of an OFDM transmission system (SYS). A first link quality measure determination unit (Q-DET) determines a first link quality measure (Q) on the basis of a signal power variation or a signal-to-noise variation determined by a variation determination unit (VS-DET). A second link quality determination unit (Q-DET) calculates a second link quality measure (Q) on the basis of an average signal-to-noise ratio based on the noise power (P) and the signal power (P). To perform a link adaptation (LA) an overall link quality determination unit (Q-DET) combines the first and second link quality measures (Q, Q) into an overall link quality measure (Q).
