OFDM Channel Simulator – C++ Educational Software is an interactive simulation tool designed to help students, educators, researchers, and communication-engineering learners understand Orthogonal Frequency Division Multiplexing (OFDM) and wireless channel effects. Developed using C++, the simulator demonstrates FFT/IFFT processing, cyclic prefix, QPSK and QAM modulation, multipath channels, delay spread, channel frequency response, equalization, BER, EVM, and constellation diagrams through an intuitive graphical interface.
