Resource Overview
ofdm.m serves as the main executable program that generates the bit error rate curve under additive noise conditions, compares it with the theoretical QPSK BER curve in additive white Gaussian noise, and demonstrates their overlap
Detailed Documentation
This document discusses the main program "ofdm.m" which, when executed, generates bit error rate curves. These curves demonstrate the accuracy of data transmission after multiple iterations under noisy conditions. The program implements a comparative analysis with theoretical QPSK BER curves under additive white Gaussian noise to identify similarities and differences. The implementation includes key functions for OFDM signal generation, noise addition, and BER calculation. When the two curves overlap, it validates that the program's results match theoretical expectations, otherwise further investigation into the program's accuracy is warranted. The code employs algorithms for subcarrier modulation, IFFT/FFT operations, and statistical BER computation using Monte Carlo simulation techniques.
