ABSTRACT:
The present invention covers the notion of determining signal dispersion characteristics, such as amplitude, phase and delay, by transmitting a training sequence. This training sequence includes a plurality of predetermined symbols and has a time duration at least equal to the expected range of the signal dispersion delay characteristic. At a receiver, the received training sequence is processed using correlation and signal replication and the aforesaid signal dispersion characteristics are determined therefrom.
