Research of anti-multi tone jamming based on OFDM video transmission system

Orthogonal frequency-division multiplexing (OFDM) technology with the DCT encoding, orthogonal coding can make the transmitted video data extended to sub-channel of the each group, and this can improve the capability of the well-narrowband jamming system. Experimental results show that, the coding method can not only make good use of the transmission of the video data, but it also has very clear-Narrowband interference robustness. And the mistakenly bit rate of system has been improved significantly.
