Multi-Carrier Broadband Digital Modulation Technology

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier broadband digital modulation technique. Compared with conventional digital communication systems, it offers advantages such as high spectral efficiency and strong resistance to multipath interference, making it suitable for high-speed wireless communication systems. Implementation typically involves IFFT/FFT algorithms for efficient parallel data transmission across orthogonal subcarriers.
