摘要
该文在介绍基本数字图像处理技术的基础之上,利用CDMA(Code Division Multiple Access)码分多址技术,实现了图像信息的传输仿真。该文的主要任务是通过运用Matlab软件实现二维DCT分块图像的压缩,并结合Zigzag编码和Huffman编码对图像信息进行了进一步处理,在QPSK调制之后利用无线收发模块(无线信道仿真)实现了图像数据的收发和验证。在仿真过程中还利用m序列,实现多个用户共用信道,增加了信道的利用率。
Pick to based on the introduction of basic digital image processing technology, on the basis of using CDMA (Code Division Multiple Access) CDMA technology, realize image information transmission simulation. This paper is the main task of the Matlab software by using 2-d DCT block image realize, combining the compression coding and Huffman coding Zigzag of image information for further treatment, after QPSK modulation in using wireless transceiver module (wireless channel simulation) realize image data transceiver and verified. In simulation process also use m sequence, implement multiple users share channel, increase the channel utilization.
