Abstract: Orthogonal Frequency-Division Multiplexing(OFDM) technology with the DCT encoding,orthogonal coding can make the transmitted video data extended to sub-bands of the each group,and this can improve the capacity 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 also have a very clear-narrowband interference robustness.And the mistaken bit rate of system has been improved greatly.
Key words: anti-multi tone jamming, Discrete Cosine Transform(DCT) encoding, Orthogonal Frequency-Division Multiplexing(OFDM), bit rate
摘要: 将视频DCT编码和OFDM技术结合起来,通过正交编码将所传输的视频数据流扩展到各组子信道中,能够很好地提高系统的抗多音干扰能力。仿真结果表明,该编码方法不仅能很好地传输视频数据,还具有明显的抗多音干扰的鲁棒性,系统的误比特率改善也得到较大地提高。
