dcthide
dct隐写技术matlab实现资料。算法原理:通过在一个图像块中调整两个DCT系数的相对大小,隐藏秘密信息。
将载体图像分为8×8的块,做二维DCT变换
用来表示选中的两个系数的坐标对于第i bit秘密信息
if(要隐藏信息‘1’)
make
else
make
逆DCT变换,还原图像
(dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)

RESEARCH_ON_TURBO_EQULIZATION
传统均衡器无法有效地同时对抗这两种信道衰落,而Turbo均衡技术作为一种联合信道均衡和信道译码的方法,能有效地对抗符号间干扰(ISI),提供迭代增益,提高接收机的整体性能。因此,本文根据下一代无线通信系统的设计要求,分别对单载波和OFDM系统的Turbo均衡算法进行了研究。
(Conventional equalizer can not effectively fight both at the same time fading, while the Turbo equalization as a joint channel equalization and channel decoding method is robust against inter-symbol interference (ISI), provides iteration gain, improved receiver overall performance. Therefore, this next-generation wireless communication system according to the design requirements, namely, the single carrier and OFDM systems Turbo equalization algorithm is studied.)
