Pseudo-random Sequence Correlation Simulation Based on MATLAB

Pseudo-random code is the basis of spread spectrum communication, at the same time, coherent receiver the spread spectrum signal by make use of the favorable correlation and reproducibility features of pseudo-random code, its can greatly improve SNR of the coherent receiver circuit output. It´s an effective way to make use of software to generates and simulates pseudo-random code, and study the character of pseudo-random code. In this paper, the m sequences and Gold sequences generated based on MATLAB/SIMULINK, and sent it to the workspace, following compile M files and call the data from workspace directly to go along the relativity of the simulation of pseudo-random code. The method has a friendly user interface, less code, and can easily modify the parameter values. The simulation results confirm the correctness, advance, simplicity of the method, and its has a greater reference value for the engineering and technical personnel.
