MATLAB Simulation of RAKE Receiver for DS-CDMA Systems

This code implements a MATLAB simulation of a RAKE receiver for DS-CDMA communication systems (complete with working source .m files). The simulation models DS-CDMA technology, which enables multi-user communication through data spreading and modulation with pseudo-random codes. The RAKE receiver structure, commonly used in DS-CDMA systems, improves reception performance by collecting signals from multiple propagation paths and combining them through weighted summation. Our implementation includes MATLAB algorithms for generating spreading codes, simulating multipath channels, and implementing the RAKE combining mechanism with maximal ratio combining. Key functions handle signal generation, correlation detection for each finger, and signal-to-noise ratio calculations. The simulation successfully demonstrates DS-CDMA operational principles and RAKE receiver performance characteristics. These tested code files and simulation results provide valuable reference material for wireless communication research and educational purposes.
