| Zusammenfassung: | The invention discloses a wireless communication system based on vortex electromagnetic wave and orthogonal frequency division multiplexing (OFDM), and mainly solves the problem that the existing system cannot resist the multi-path effect. The wireless communication system comprises a transmitting-end vortex electromagnetic wave OAM (Orbital Angular Momentum) mode former (1), a transmitting-end radio-frequency link module (2), a uniform circular transmitting antenna array (3), a uniform circular receiving antenna array (4), a receiving-end radio-frequency link module (5) and a receiving-end vortex electromagnetic wave OAM mode decomposer (6); after the transmitting-end vortex electromagnetic wave OAM mode former performs IFFT operation on an input data block, modulation of OFDM and the mode number of the OAM are generated, provided for the link module, and transmitted through the antenna array; and, the receiving-end vortex electromagnetic wave OAM mode decomposer performs FFT operation on a received data blo |
