CODE DIVISION MULTIPLE ACCESS SIGNAL TRANSMITTER, CDMA NETWORK BASE STATION AND TERMINAL COMPRISING SUCH A TRANSMITTER

摘要

The invention concerns a signal transmitter ensuring the simultaneous transmission of n digital signals (S1 to Sn) to receivers. Each of the n digital signals (S1 to Sn) is stretched by combining with a stretching sequence (W1 to Wn) and the stretched signals are applied to an adder circuit (11) supplying a resulting sum signal. The sum signal is applied to a modulator (12) with continuous phase supplying a modulated signal (SM) to a power amplifier (13). The invention is useful for limiting interference between adjacent channels.
