Title: Discriminating method of correlation value
Inventor: TANDA KAZUTADA
IPC: H04B1/707
Filed: 2001-09-28
Abstract: PROBLEM TO BE SOLVED: To discriminate a false signal mutual correlation and a weak signal time correlation. SOLUTION: A correlation peak value is detected by a first correlator that detects the correlation peak value in one epoch unit.

When the correlation peak value in one chip unit is a weak signal maximum threshold or larger, the received signal related with the correlation value is considered to be relatively strong and not buried in noises so that it is determined that the correlation peak value depends on the false signal mutual correlation, and the synchronization is not established.  When the correlation peak value in chip unit is the weak signal maximum threshold or smaller, the received signal related with the correlation value is considered to be relatively weak and buried in noises so that it is determined that the correlation peak value depends on the weak signal time correlation, and the synchronization is established (205).
