Estimating the term…
In order to compensate for a frequency offset or a change in the phase of the transmission channel over time during mobile radio transmission of data symbols, the data symbols are transmitted by means of carrier-frequency, modulated data bursts. Sample values of the received signal, which are known in advance and correspond to first and second symbols, are evaluated in order to estimate the frequency offset or the change in the phase of the transmission channel over time. These first and second symbols are transmitted with a defined phase angle by means of the data burst, and are arranged separated from one another in the data burst. Edge symbols in a data burst are advantageously used as first and second symbols, or as a symbol pair, for estimation.
Method for receiver-end compensation for a frequency offset or for a change in the phase of the transmission channel over time during mobile radio transmission of data symbols, comprising:
A receiving unit for the reception of data symbols in carrier-frequency, modulated data bursts and for compensation thereof for a frequency offset or for a change in the phase of a transmission channel over time during mobile radio transmission, comprising:
