MATLAB Source Code for SNR to Eb/N0 Conversion with BER/SER Analysis and Plotting

This MATLAB source code primarily converts Signal-to-Noise Ratio (SNR) to Bit Error Rate (BER) or Symbol Error Rate (SER), with integrated plotting capabilities for generating BER/SER performance curves. The implementation includes calculation methods for Frame Error Rate (FER) and Symbol Error Rate (SER), along with text output functionalities that display computed results such as error rates and bit error probabilities. The code features configurable options allowing users to select different modulation schemes (including BPSK, QPSK, 16QAM) and various coding techniques (such as convolutional codes, LDPC codes) for customized performance analysis. Key algorithmic components involve theoretical BER/SER calculations based on digital communication theory, with plotting functions utilizing MATLAB's graphics toolkit to visualize performance metrics. This versatile MATLAB tool is particularly valuable for digital communication system design and performance evaluation, offering both analytical computations and graphical representations of system behavior under different signal-to-noise conditions.
