SIGNAL FRAME, METHOD FOR SYNCHRONIZING THE SAME, TRANSMITTER AND RECEIVER OF TELECOMMUNICATIONS SYSTEM, AND THE TELECOMMUNICATIONS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for synchronizing a signal frame by a synchronization sequence, in connection with a telecommunications system.

SOLUTION: A synchronization sequence (xi(k)) is formed by concatenation of first and second bursts of L complementary sequences by a transmitter, and the first burst of L sequences is obtained by concatenation of a first complementary sequence (A) of N pulses of a pair of complementary sequences ((A, B)) by L times. The second burst of L sequences is obtained by concatenation of a second complementary sequence (B) of N pulses of the pair of complementary sequences by L times. Multiplication is performed by a component of rank q of L component length weighting code (MCi), belonging to a set of I weighting codes that have been known by a receiver (RCD) beforehand, and the pulses of each sequence of rank q of the second burst of L sequences are multiplied by the same component of rank q of the weighting code (MCi).
