ABSTRACT:
The present invention relates to a method and a circuitry for estimating data transmission rate in a communication system. The communication system utilizes variable data transmission rates. A transmission signal between two stations of the system includes a plurality of data symbols over a sequence of data frames. A data frame of a received transmission signal is classified in accordance with a predefined classification of the data transmission rates, whereafter the data transmission rate of the received data frame is estimated on basis of said classification.
