Key Technology
OFDM (Orthogonal Frequency Division Multiplexing) is essentially a multicarrier modulation technique derived from MCM (Multi-Carrier Modulation). The modulation and demodulation processes are implemented using IFFT and FFT operations respectively, making it one of the most efficient and widely adopted multicarrier transmission schemes with minimal implementation complexity.

Key Technology
OFDM (Orthogonal Frequency Division Multiplexing) is a multicarrier modulation technique that evolved from MCM technology. As one of the most efficient multicarrier transmission implementations, OFDM utilizes IFFT (Inverse Fast Fourier Transform) for modulation and FFT (Fast Fourier Transform) for demodulation. This approach minimizes implementation complexity while maintaining spectral efficiency, making it the most widely adopted multicarrier solution in modern wireless communication systems. The simulation demonstrates key algorithms including cyclic prefix insertion, subcarrier mapping, and channel equalization techniques.
