MODULE FOR DETERMINING THE GROUP GAIN AND DELAY ASSOCIATED WITH A TRANSFER FUNCTION OF A TRANSMISSION CHANNEL IN A CDMA COMMUNICATION SYSTEM

摘要

the invention relates to a module (22) for determining the gain and the time of group associated with a transfer function of a transmission channel (16) in a cdma communication system (10) comprenas at least one data transmitter (12) and the receiver (s) (14) / cdma cdma data, the receiver (14) of data (s) comprising a cdma module (22) for determination.the transmitter (12) of cdma is given (s) to transmit a signal including at least one cdma cdma spreading code is representative of a bit of the data, the code spreading cdma is memorized.first, the receiver (14) of the data (s) comprising n elements of three.the module (22) includes a tool for comparison of determination to compare in real time and, at the same time, the transmission of cdma signal, the phase and the amplitude.the spectrum of the received signal (sr) of the cdma receiver (14) with a signal (a) cdma spectrum spreading code for cdma with the memorized.
