trans_sigPnoisePinterference
根据直扩原理,首先有随机数发生器产生一系列二进制信息数据(+1,-1),每个信息比特重复Lc次,Lc对应每个信息比特所包含的伪码片数,包含每一比特Lc次重复的序列与另一个随机数发生器产生的PN序列c(n)相乘。然后在该序列上叠加高斯白噪声和形式为i(n)=Acosw0n余弦干扰下次信号,切余弦干扰信号的振幅满足条件A<Lc。在解调器中进行与PN序列的互相关运算,并且将组成各信息比特的Lc个样本进行求和。加法器的输出送到判决器,将信号与门限值0进行比较,确定传送的数据为+1还是-1,计数器用来记录判决器的错判数目。(According to the principle, first some straight expansion random number generator produces a series of binary data (+ 1-1), each information bit repetitive Lc times, Lc for each information bit contains PN code piece count, embraces each bit Lc times repeated sequence and another random number generator produces PN sequence c (n) multiplication. Then in the sequence superimposed on gaussian white noise and forms as I (n) = Acosw0n cosine interference next time signal, cut cosine interfering signal amplitude satisfy conditions A < Lc. In the modem with the cross-correlation operation PN sequence, and the information will comprise the Lc a sample bits peace. The output of the adder judgment device, will signal to compare with threshold 0 data transmitted, determine for+ 1 or-1, counter is used to record the number victimised judgment.

MP3-watermarking
说明: :针对MP3 编码方式和帧结构进行分析,利用帧中的比例因子提出了一种压缩域水印算法。算法通过引入帧变化分析步
骤,很好地实现了水印的自适应嵌入。对于不同的系统要求,还可以通过修改门限信噪比的值SNRlim按需进行水印嵌入,使算法
具有更大灵活性。同时在牺牲一定的嵌入空间前提下,实现了水印信息的自同步。实验表明,对于不同风格的音乐,该水印算法
具有很好的不可听性。(In this paper,the encoding method and the frame structure of MP3 are expounded in detail,a watermark algorithm
is proposed based on the scale factor in MP3 frame.By introducing the step of frame altering analysis,the algorithm
can realize that watermarks is embedded adaptively.By modifying threshold SNRlim(the ratio of signal to noise),the algorithm
can meet different requirements of some system,that is what enable the algorithm to have a bigger flexibility.Based on expense
of some embedding positions,the watermark can be embedded with self-synchronization.The experiment results show
this algorithm can get a good audio effect with various types of audio.)
