Encoding & Decoding of message seq using (n,k) Systematic Linear Block Code.

说明：  本书是“移动通信前沿技术系列”之一，全书共分18个章节，主要对协作通信及网络知识作了介绍，具体内容包括空时分集和编码、空时频分集与空时频编码、中继信道及协议、单中继协作通信、多节点协作通信等。全书内容分为三部分，第一部分回顾传统的MIMO系统，介绍空间、时间、频率分集的概念。第二部分主要考虑协作通信物理层的关键问题，并对其提出了行之有效的解决方案，比如针对协作通信的分布式特点，提出分布式空时(频)码；针对协作通信的频谱效率问题，提出了新颖和有效的协作方案。第三部分介绍协作通信对物理层之上的MAC层、网络层及应用层产生的影响，内容涉及如何协作路由，如何通过协作使网络覆盖范围增大，如何延长网络寿命等。(This book is one of the "cutting edge mobile communication technology series". The book is divided into 18 chapters, mainly on cooperative communications and network knowledge and specific content including the empty hours of collection and coding, space-time-frequency diversity and space-time frequency coding, relay channel and protocols, single-relay cooperative communication, multi-node cooperative communications.)

基于语音信号处理的MATLAB平均幅度差函数，比自相关函数计算量要少。(Based on the average amplitude of the speech signal processing functions, less than the autocorrelation function computation.)

1. this function is for image (width=176, hight=144) only. but you can modify the related value to fit yours. 2. it is used to evaluate the motion vector between the Nth image and N-1th image. 3. it use Three Steps search algorithm. 4. this algorithm finds the closest pixel near the original pixel in three times.(1.
