说明： Owing to the broad application value of audio
watermarking in remote transmission and mobile
extraction, it is very important to study watermarking
approaches against A/D and D/A conversion. Based
on wavelet decomposition and cepstrum technology,
an audio watermarking algorithm is proposed where
the low-frequency wavelet coefficients are chosen for
cepstrum transforming. Then, the obtained cepstrum
data shows stable for watermark hiding by the
methods of edging data cutting and statistical mean
modification. The synchronization is not required in
the algorithm. Experimental results show that the
proposed algorithm can resist on the attack of A/D
and D/A successfully with features of large capacity
and zero bit error. It will be helpful for the mobile
audio in secure broadcast and management in the

Proteus090408
Proteus 仿真软件在单片机设计中的应用(摘 要 单片机应用技术所涉及到的实验实践环节比较多，而且硬件投入比较大。在具体的工程实践中，如果因为方案有误而进
行相应的开发设计，会浪费较多的时间和经费。Proteus 仿真软件很好的解决了这些问题，他可以象Protel 一样画好硬件原理图
与KEIL 编程软件结合进行编程仿真调试。)

TCPIPTutorial
In the TCP/IP protocol suite, TCP is the intermediate layer
between IP below it, and an application above it. Using TCP,
applications on networked hosts can establish reliable
connections to one another. The protocol guarantees in-order
delivery of data from the sender to the receiver
Streams of data called segments are used by TCP peers to
speak to each other. The segments can be quite large, so TCP
breaks up the segments into smaller units of data. These units
are encapsulated in the TCP packet that is passed to the IP
protocol. Each unit of data is assigned a sequence number,
which becomes part of the TCP packet. At the receiving end, the
TCP module uses the sequence numbers in the packet to
reconstruct the user data in the correct order.
