基于电视体制的人在回路制导链路研究

Research on guidance link of “man in loop”based on video guidance system

在"人在回路"电视制导链路中,需要对海量的图像数据进行快速的传输和实时的处理,其实现通过对单帧黑白图像进行DCT离散余弦变换,量化后,采用差分截尾的哈夫曼熵编码方式,实现图像压缩,物理链路采用卷积码信道编码,基于直序扩频以及键控频通信体制,以MATLAB仿真验证了该通信模型的可行性。

In the ＂ man in loop＂ TV guidance link, fast transmission and real-time processing are needed for giant image data. for one frame monochrome image, it should be done discrete cosine transform（DCT）, and the DCT matrix will be lighten, then using differential censoring and Huffman coding to achieve the data compressing. Physical link takes in the convolution coding, based on DSSS and MSK. At last,it verifies the feasibility of this communication model by MATLAB simulation.
