Instead of sending data on a single carrier, the OFDM modem splits the input data stream into multiple parallel streams and modulates each stream onto a different sub-carrier using techniques such as Quadrature Amplitude Modulation (QAM) or Phase Shift Keying (PSK). These sub-carriers are mathematically orthogonal, meaning they can overlap in the frequency domain without causing interference, which significantly improves spectral efficiency. The modem employs digital signal processing techniques like the Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) for efficient modulation and demodulation of the signals. To combat channel impairments such as multipath fading and inter-symbol interference, the OFDM modem typically incorporates a cyclic prefix and channel estimation algorithms. Due to its robustness and high data throughput capability, OFDM technology is widely used in modern communication standards such as Wi‑Fi (IEEE 802.11), 4G LTE, 5G NR, and Digital Video Broadcasting (DVB) systems. Overall, an OFDM modem plays a critical role in enabling reliable, high-capacity communication in broadband networks by maximizing bandwidth utilization and maintaining performance even in challenging transmission environments.
