| Abstract: | This paper illustrated the theory and operational process of WCDMA uplink channel's spead spectrum and modulation.The simulation module of WCDMA uplink channel was founded by MATLAB,then the result of the simulation was given.Based on the preceding study and simulation it was concluded that the OVSF used in WCDMA could primely solve the problems of different operation's transmission and multi users' disturbance. |
