Abstract
The invention relates to a TDMA method, transmitter and receiver, wherein a training sequence is modulated and superposed on a data signal to thereby generate a TDMA burst. Thereby, the training sequence can be made longer and is always available during data reception, such that longer channel impulse responses can be measured. In the transmitter, the training sequence is separately modulated in a modulating means ( ) before being superposed on the data signal. The receiver comprises an extracting means ( ) for extracting the superposed training sequence and a cancelling means ( ) for cancelling the training sequence from the data signal to be detected.
