代码说明:

  完整的OFDM链路程序并作了较为具体的解析从基本的bpsk,qpsk,qam到实际的ofdm系统,cdma链路,mac层仿真分析.(Orthogonal frequency division multiplexing (OFDM) is becoming the chosen modulation technique for wireless communications. OFDM can provide large data rates with sufficient robustness to radio channel impairments. Many research centers in the world have specialized teams working in the optimization of OFDM for countless applications. Here, at the Georgia Institute of Technology, one of such teams is in Dr. M. A. Ingram’s Smart Antenna Research Laboratory (SARL), a part of the Georgia Center for Advanced Telecommunications Technology (GCATT). The purpose of this report is to provide Matlab code to simulate the basic processing involved in the generation and reception of an OFDM signal in a physical channel and to provide a description of each of the steps involved. For this purpose, we shall use, as an example, one of the proposed OFDM signals of the Digital Video Broadcasting (DVB) standard for the European terrestrial digital television (DTV) service.)

  • viewer3d_version9a
    This function(s) can be used to interactively view any kind of 3D image volumes like CT and MRI, and for distance measurements or ROI selection in 2D slices. It includes Maximum intensity projections (MIP), Volume Rendering (VR) , Slice render, and colored and Phong shaded Volume rendering. Voxel opacity and color tables can be changed on the fly allowing also iso surface kind of renders. The fast render algorithm which renders a 3D volume to a 2D image, is based on a Matlab coded implementation of the Shear-Warp transform, in which instead of rotating the viewer rays the slices are sheared.

  • Cooperative-communication
    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.)
