Bit Error Rate Performance Simulation of Spreading Sequences

The MATLAB-based simulation program for analyzing bit error rate performance of spreading sequences represents a core component of this research. This simulation tool enables comprehensive evaluation of spreading sequence performance through BER (Bit Error Rate) analysis under various channel conditions. The implementation typically involves generating spreading sequences using functions like pnsequence or goldseq, modulating transmitted signals with these sequences, and simulating AWGN or multipath channels using built-in MATLAB functions. Users can customize critical parameters including spreading factor, signal-to-noise ratio ranges, modulation schemes, and channel models through configurable input variables. The program incorporates performance monitoring features that track key metrics such as BER curves, correlation properties, and power spectral density. Before executing simulations, ensure proper installation of MATLAB with Communications Toolbox and Signal Processing Toolbox dependencies. The simulation workflow includes signal generation, spreading sequence application, channel impairment modeling, receiver processing with correlation detection, and error counting algorithms. Results can be visualized through MATLAB plotting functions to analyze performance trends and optimize sequence selection. This versatile tool provides researchers and engineers with practical insights for understanding and enhancing spreading sequence characteristics in communication system design.
