Abstract:
1. 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: configuring a data burst prior to transmission with first and second symbols that are known at a receiver end, the first and second symbols having a defined phase angle and being arranged separate from one another in the data burst; transmitting the data burst containing the data symbols to the receiver end; and using parts of the transmitted data burst at the receiver end that correspond to the first and second symbols to compensate for the frequency offset or for the change in the phase of the transmission channel over time in the respective received data burst; wherein the frequency offset is determined by solving an equation system based on a channel impulse response and a number of known edge symbols; and wherein the number of known edge symbols is greater than the order of the channel impulse response.
