OFDM Orthogonal Frequency Division Multiplexing

Multi-carrier parallel transmission, resilient to multipath

Real-World Applications

4G LTE, 5G NR, WiFi (a/g/n/ac/ax), digital TV (DTMB/DVB-T). OFDM can overcome multipath fading, the absolute core waveform technology of modern broadband wireless communications.

Experiment Steps

1. Numerology: Δf = 15kHz × 2^μ
2. Resource Grid: Per PRB = 12 Subcarriers
