ABSTRACT:
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 the received signal frame and the locally generated training sequence. A center of energy value is calculated for a first vector having M correlation values. A second vector having N consecutive correlation values distributed around the center of energy is chosen to form the channel estimate. The center of energy in the second vector can be chosen as synchronizing position.
