GAIN AND GROUP DELAY DETERMINATION MODULE ASSOCIATED WITH TRANSMISSION CHANNEL TRANSMISSION FUNCTION OF CDMA COMMUNICATION SYSTEM

摘要

The invention relates to a module (22) for determining the gain and the group delay associated with a transfer function of a transmission channel (16) of a CDMA communication system (10) comprising at least one transmitter (12). ) of CDMA data (s) and a CDMA data receiver (14), the CDMA data receiver (14) comprising the determination module (22), the CDMA data transmitter (12) being capable of transmitting a CDMA signal comprising at least one spreading CDMA code, representative of a data bit, the spreading CDMA code being stored in advance by the CDMA data receiver (14) and comprising n elements, the determination module (22) comprising a comparison tool capable of comparing in real time and simultaneously with the transmission of the CDMA signal, the phase and the amplitude, of the spectrum of the signal (SR) CDMA received by the receiver ( 14) with the expected CDMA signal spectrum (SA) associated with the stored spread CDMA code .
