PAPR

OFDM Simulator – C++ Educational Software is an interactive learning and simulation tool for understanding Orthogonal Frequency Division Multiplexing (OFDM) and digital communication concepts. Developed using C++, it allows users to configure FFT/IFFT size, active subcarriers, cyclic prefix length, modulation, SNR, and number of OFDM symbols while visualizing the resulting time-domain waveform, spectrum, and constellation. The simulator also provides measurable results such as PAPR, BER, Eb/N0, simulated bits, and cyclic-prefix overhead.
