Ternary-Sequence-Based-OFDM-Frame-Synchro-in-WIFI
In this paper, we present and analyze efficient frame synchronization and frequency offset compensation scheme with ternary sequences for an orthogonal frequency division multiplexing (OFDM) system in Rayleigh fading channels. Frame
synchronization is an essential procedure for normal operation of
the OFDM system because of sensitivity to synchronization errors. And when there are frequency offsets in OFDM frame, the loss of
orthogonality occurs and the interference problem among several subcarriers is introduced. These fact leads to the requirement for joint implementation of the frame synchronization and frequency offset compensation.

H.264/AVC is the current video standardization project of the ITU-T Video Coding
Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). The
main goals of this standardization effort are to develop a simple and straightforward
video coding design, with enhanced compression performance, and to provide a
鈥渘etwork-friendly鈥?video representation which addresses 鈥渃onversational鈥?(video
telephony) and 鈥渘on-conversational鈥?(storage, broadcast or streaming) applications.

DotNETFrameworkEssentials
程序员将会非常喜欢.NET框架精髓这本书，这本书用简练的语言系统、彻底的讲解了使用.NET框架创建网络应用程序和网络服务所必须了解的技术细节。和其他一些类似文档不同的是，这本书减掉了很多夸大其词或者不相关的杂音，从而提供了清晰、使用的技术知识。(programmers will be very fond of.NET framework essence of this book, this book with concise language, thorough presentation use.NET framework for creating network applications and network services to be aware of the technical details. And other similar documents is different is that this book lose a lot of exaggeration or not related to the noises. thus providing a clear, the use of technical knowledge.)
