This program simulates a basic CDMA communication system using Matlab. It includes the following components:

cdma.m is the main file

Four .wav files to simulate four users (variables x1, x2, x3 and x4)

nivel: the number of levels for quantization.

opcion: quantization processes. Available options:

• 1 - Uniform
• 2 - Mu-Law
• 4 - A-Law

opt: type of code for CDMA access. Available options:

• 1 = Orthogonal (Synchronous)
• 2 = Random (Asynchronous)

gp: GP value for correlation matrix

You can select to play one user voice or all users

This program was developed during the communication course "Comunicación y codificación digital" at Universidad de las Fuerzas Armadas ESPE.
