Estimating the optimal sampling instant in a TDMA packet transmission system

摘要

The invention relates to a system for transmitting TDMA packets between interactive terminals and a head station via a transmission medium, in which the receiver effects a oversampling of the received signal so as to retrieve the optimal sample corresponding to the transmitted symbol. The invention proposes a method of recovering this optimal sampling instant very rapidly by performing a polynomial interpolation computation between the generated oversamples so as to derive the optimal sampling instant and by filtering the received signal by means of a low-pass filter centered at the optimal sampling instant.
