CDMA Module Simulation

This project involves the simulation of CDMA (Code Division Multiple Access) modules to facilitate better understanding and research of CDMA technology principles. During the simulation process, we will model CDMA signal transmission and reception using spreading codes and correlation detection algorithms. The implementation will include generating orthogonal codes (such as Walsh codes) for multiple users, simulating the modulation process using BPSK or QPSK schemes, and adding AWGN (Additive White Gaussian Noise) to the channel. We will explore how different parameters like spreading factor, signal-to-noise ratio, and number of simultaneous users affect system performance metrics such as bit error rate (BER) and capacity. The simulation code will incorporate key functions for signal generation, correlation-based detection, and performance analysis. By analyzing the results through BER curves and constellation diagrams, we can draw meaningful conclusions about CDMA system behavior. This simulation experiment provides deep insights into CDMA technology and establishes a solid foundation for subsequent research and development work.
