In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn t kept waiting any longer than necessary for the relatively slow disks.

There is an example of how to use the LDPC encode/decode with AWGN channel model in files .\ldpc_decode.m and .\GFq\ldpc_decode.m. There are a few parity check matrices available in the code but you can use other matrices provided you have enough memory to load them. I suggest checking out matrices in Alist format available on David MacKay s web site.You will need to have access to a MEX compiler to be able to use a few functions written in C. LDPC的仿真代码

This m-file simulates MPSK (theoretical and simulated) with Gray coding This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).

This lab exercise will cover the use of AccelDSP’s design exploration capabilities that include mapping variables to memory and unrolling loop and vector operations. You will learn how to create different hardware architectures without modifying the MATLAB source to explore different area/performance tradeoffs.

1、链接存储方法 链接方式存储的线性表简称为链表（Linked List）。 链表的具体存储表示为： ① 用一组任意的存储单元来存放线性表的结点（这组存储单元既可以是连续的，也可以是不连续的） ② 链表中结点的逻辑次序和物理次序不一定相同。为了能正确表示结点间的逻辑关系，在存储每个结点值的同时，还必须存储指示其后继结点的地址（或位置）信息（称为指针（pointer）或链(link)） 注意： 链式存储是最常用的存储方式之一，它不仅可用来表示线性表，而且可用来表示各种非线性的数据结构。

penMesh is a generic and efficient data structure for representing and manipulating polygonal meshes. OpenMesh is developed at the Computer Graphics Group, RWTH Aachen , as part of the OpenSGPlus project, is funded by the German Ministry for Research and Education ( BMBF), and will serve as geometry kernel upon which the so-called high level primitives (e.g. subdivision surfaces or progressive meshes) of OpenSGPlus are built. It was designed with the following goals in mind : Flexibility : provide a basis for many different algorithms without the need for adaptation. Efficiency : maximize time efficiency while keeping memory usage as low as possible. Ease of use : wrap complex internal structure in an easy-to-use interface.

RAM Disk Driver with custom BoundsChecker events This sample illustrates how to add custom BoundsChecker events to a DDK driver. It links to the kchecker library and has several BOUNDSCHECKER() calls in it. This sample is a software only Windows NT Device Driver. This driver is provided for educational purposes only. Generally the Windows NT cache manager does a much better job of optimizing memory usage than using a RAM disk.
