📡 OFDM Subcarrier Spectrum (2D)

2D OFDM simulator: N orthogonal subcarriers at integer multiples of a base frequency are summed into a composite time-domain waveform, with a live magnitude-spectrum view. Adjust subcarrier count, amplitude, phase and symbol rate.

⚙ Under the hood

This 2D Canvas simulation sums N orthogonal subcarrier waves, each at an integer multiple of a base frequency f0, into one composite time-domain OFDM waveform, and plots their magnitudes as a spectrum below it. You can change subcarrier count, base frequency, symbol rate and modulation order, and watch the composite signal and spectrum update live.
