MATLAB Simulation of Spread Spectrum Transceiver

This document presents a MATLAB simulation program for a spread spectrum transceiver system, incorporating synchronization through matched filter methodology. Spread spectrum transceivers are devices that expand signal bandwidth by multiplying the original signal with a spreading code at the transmitter side, thereby distributing the signal across a wider frequency band. At the receiver end, the spread spectrum signal undergoes despreading through a matched filter, enabling recovery of the original signal. The simulation implements this complete process through MATLAB programming, featuring key algorithmic components including pseudorandom sequence generation for spreading codes, correlation-based detection algorithms, and synchronization threshold calculations. The implementation demonstrates practical code techniques such as cross-correlation operations using MATLAB's xcorr function, FIR filter design for matched filtering, and bit error rate (BER) performance evaluation. Detailed procedural steps and comprehensive code examples are provided to facilitate better understanding and practical application of spread spectrum transceiver technology, including real-time signal processing simulations and performance analysis metrics.
