Resource Overview

This code performs Bit Error Rate (BER) simulations for both BPSK and QPSK modulation schemes across various Signal-to-Noise Ratio (SNR) values. The simulation transmits at least 10^6 bits for statistical reliability and evaluates performance across 10 different SNR iterations to generate comprehensive BER curves.

Detailed Documentation

This article presents a comprehensive BER simulation code capable of analyzing both BPSK (Binary Phase Shift Keying) and QPSK (Quadrature Phase Shift Keying) modulation schemes under varying SNR conditions. The implementation features Monte Carlo simulation methodology where each SNR point processes a minimum of 10^6 transmitted bits to ensure statistical significance. The simulation sweeps through 10 distinct SNR values in iterative fashion, employing AWGN (Additive White Gaussian Noise) channel modeling and coherent detection. Key algorithm components include symbol mapping/demapping routines, noise variance calculation based on SNR values, and error counting mechanisms comparing original and received bit streams. The modular code structure allows easy extension to other modulation schemes while maintaining accurate BER performance analysis.
