对于无线通信系统中,MIMO OFDM信道估计技术的研究,实现。
source and channel coding present competing objectives of reducing bandwidth while minimizing distortion in the video stream
Associating the video bit-stream with forward error correction (FEC) for error detection and correction can overcome the problem.
Join the leagues of thousands of programmers and learn C++ from some of the best. The fifth edition of the best seller Sams Teach Yourself C++ in 21 Days, written by Jesse Liberty, a well-known C++ and C# programming manual author and Bradley L. Jones, manager for a number of high profiler developer websites, has been updated to the new ANSI/ISO C++ Standard. This is an excellent hands-on guide for the beginning programmer. Packed with examples of syntax and detailed analysis of code, fundamentals such as managing I/O, loops, arrays and creating C++ applications are all covered in the 21 easy-to-follow lessons. You will also be given access to a website that will provide you will all the source code examples developed in the book as a practice tool. C++ is the preferred language for millions of developers-make Sams Teach Yourself the preferred way to learn it!
A stream is a fundamental abstraction in programming: a sequence of bits transmitted serially from one point to another point. Cocoa provides three classes to represent streams and facilitate their use in your programs: NSStream, NSInputStream, and NSOutputStream. With the instances of these classes you can read data from, and write data to, files and application memory. You can also use these objects in socket-based connections to exchange data with remote hosts. You can also subclass the stream classes to obtain specialized stream behavior.
