Abstract :
The communication model of DSSS is built through Simulink, in which the M-DPSK modem technology and the convolutional encoder are adopted. The antinoise performance on AWGN channel is studied on the different spread spectrum sequence code and different spread spectrum gain. The modulate methods can choose exactly in actual CDMA system and improve the quality of communication.
