Abstract:
1. A method for motion-compensated noise evaluation for mobile wireless transmission systems, in which reference symbols are sent out by a transmitter ( 1 ), comprising: determining a static component of the received reference symbols by forming a statistical moment from at least some of the reference symbols following each other directly or indirectly in time and received in a receiver; determining a dynamic component of the received reference symbols by comparing at least two directly or indirectly time-consecutive reference symbols; computing a prediction value for the next reference symbol received from the static and the dynamic component of the received reference symbols; after receiving the next reference symbol, this received reference symbol is compared to the prediction value to determine a prediction error; determining from the prediction error an estimate for noise of a data signal transmitted in a transmission channel; and by taking account of the prediction error, the calculation of the prediction is adapted to time changes in the transmission channel.
