OFDM Simulation Parameters

The OFDM simulation parameters used in this document include: - Number of subcarriers: 128 (Typically implemented using IFFT/FFT operations with size matching subcarrier count) - Bits per symbol: 2 (Each symbol carries 2 bits of information, corresponding to 4-QAM constellation) - Symbols per carrier: 1000 (Total data symbols transmitted per subcarrier in the simulation) - Training symbols: 0 (No pilot symbols used for channel estimation in this configuration) - Cyclic prefix length: 8 samples (equivalent to 1/16 of symbol duration T, implemented by prepending the last samples to OFDM symbols) - Modulation scheme: 4-QAM (Quadrature Amplitude Modulation with 4 constellation points, mapping 2 bits per symbol) - Multipath channel count: 3 (Three-tap channel model simulating multipath propagation effects) - IFFT Size: 128 (Inverse Fast Fourier Transform size matching the number of subcarriers for OFDM modulation) - Maximum channel delay: 2 samples (Maximum delay spread in the multipath channel model) These parameters define the key simulation setup for OFDM system performance evaluation, where the IFFT/FFT implementation handles orthogonal subcarrier modulation/demodulation, while cyclic prefix insertion mitigates inter-symbol interference in multipath environments.
