Research of Direct Sequence Spread Spectrum Communication System Based on MATLAB

This paper described the theory which based on the spread spectrum communication system, a simulation model was designed based on MATLAB, and each module of the model was briefly introduced. In a particular simulation condition, ran the simulation program, and an expected result was obtained. Meanwhile, by design a spread spectrum communication system of two users, detect the bit error rate corresponding with the two users in different bit error rate (SNR), directly verified the validity of the model system.
