    摘要： A method and a device of providing timing information within a wireless communication system is described. The timing information is extracted from a received transmit signal. The inventive method comprises the steps of providing a training signal on the receiver side relating to a known signal portion of the transmit signal, scaling the training signal, quantizing the scaled training signal, correlating one or more parts of the received transmit signal with the scaled training signal to obtain one or more correlation results, and determining the timing information on the basis of the correlation results.

    摘要： A frequency tracking device (FTD) in particular for use in a OFDM communication system comprises a selector (SEL) which selects on the basis of N channel coefficients (Cest) a number M of subcarriers corresponding to the M channel coefficients (Cest) having the largest absolute values. An evaluator (EVAL) of the frequency tracking device (FTD) determines a frequency deviation estimate (foff,est) on the basis of the selected M subcarriers and the selected M channel coefficients. In addition to or instead of a feedback correction unit (CORR1) provided upstream of a multi-carrier filter bank (8; FFT), the frequency tracking device (FTD) can also comprise a feed forward correction unit (CORR2) provided downstream of the receiver multi-carrier filter bank (8). In this case the selector (SEL) and the feed forward correction unit (CORR2) operate on the same data symbols such that the correction unit (CORR2) corrects the same data symbols which are subject to the selection and evaluation process in the selector (SEL) and the evaluator (EVAL). Based on the selection and evaluation processes frequency deviations (foff) which are introduced into multi-carrier symbols when being transmitted between a transmitter multi-carrier filter bank (4; IFFT) and a receiver multi-carrier filter bank (8; FFT) can be corrected more efficiently, e.g. with a reduced computational complexity.

    摘要： In a process for demodulation of a received signal that contains, in addition to data to be transmitted, a preset synchronization sequence, the following is done to estimate a frequency shift. At least two nonoverlapping partial sequences of the synchronization sequence are picked off. Using a least-square process, the coefficients of the channel step response at each observation window are determined. The frequency shift, in the form of a phase rotation per symbol, is then estimated.
