【Abstract】 Based on the theory of system divisibility, the technology of alternative graphics modeling and the mechanism of orthogonal frequency division multiplexing (OFDM) communication, the authors studied the graphics modeling and visual emulation of OFDM. Adopting the visual emulation scheme of the system with the lamination and hierarchical structure, they constructed the visual emulation platform of OFDM system and gave the system emulation resuts under the AWGN channel. The experiment has proved that the visual emulation scheme is a quick and convenient modeling scheme with high-degree automation.更多还原
