SAETT FOER SYNKRONISERING OCH KANALESTIMERING I TDMA- RADIOSYSTEM

摘要

The invention relates to a method of synchronizing a received signal frame in a TDMA radio system with a locally generated (TR) training sequence and of determining a channel estimate based on the comparison of the received signal frame and the locally generated training sequence. A first vector comprising M correlation values is calculated. In this vector the position mw of the centre of energy is determined. A second vector comprising N consecutive correlation values distributed around the centre of energy mw is chosen to form the channel estimate. The centre of energy in the second vector can be chosen as synchronizing position.
