Title: COMMUNICATION DEVICE AND METHOD FOR JOINT OFFSET ESTIMATION
Abstract:
A communication device (10) for determining a timing offset and a frequency offset of a received signal, received through a communication channel is provided. The communication device (10) comprises a cross correlator (12), configured to perform a cross correlation of channel estimates of the communication channel, and thereby determine at least two cross correlation matrix. Moreover, the communication device (10) comprises a joint estimator (13), configured to jointly estimate the timing offset and the frequency offset of the received signal based upon the determined at least two cross correlation matrix.
