Abstract: A method for estimating round-trip time (RTT) values for data packets travelling in a telecommunication network is disclosed. During a first time interval (206) which begins with the start of a data transmission, estimated RTT values (14) are generated by filtering a periodic sequence of RTT samples (12) with a self-initializing expanding memory polynomial (EMP) filter (16) and, after a first switch-over time at the end of the first time interval, the estimated RTT values are generated by filtering the RTT samples with a fading memory polynomial (FMP) filter (18). The first switch-over time is determined by comparing an FMP estimation error and an EMP estimation error, where the FMP estimation error is the difference between an output of the FMP filter and the RTT samples, and the EMP estimation error is the difference between an output of the EMP filter and the RTT samples, and triggering the first switch-over time when the FMP estimation error becomes equal to or less than the EMP estimation error.
