一篇关于“MATLAB环境下控制系统实时仿真实验的研究”的大论文，很详细。(Essay on " MATLAB environment control system for real-time simulation of a" big paper in great detail.)

用Matlab仿真直接序列扩频系统,M文件编译，附带PPT说明(Matlab simulation with direct sequence spread spectrum system, M files to compile, with notes PPT)

这个函数得到一个形象的名字，应该是RGB，加载它并创建一个。与透明色的RGB图像的PNG地方是白色的。 如果第三个参数是setted黑色的非透明区域的功能将颜色(This functions gets an image name which should be RGB, load it and create a .png with transparent color where the RGB image is white. If the third parameter is setted the function will color in black the non-transparent areas)

。并行级联LDPC码是由多个码率不同的子码，经并行级联后得到的码率可变的LDPC码。本文提出了基于 并行级联LDPC码的递增冗余HARQ方案，给出了这种方案的吞吐量性能封闭解。在AwGN信道和Rayleigh衰落信 道下，通过仿真将新方案的性能和随机LDPC码的性能进行了比较。结果显示，并行级联LDPC码的递增冗余HARQ 方案性能接近随机LDPc码，但编、译码更简单，参数选择范围更广。(. Parallel Concatenated LDPC code is different by a plurality of bit-rate sub-code, the LDPC code rate is variable obtained after parallel concatenation. In this paper, the incremental redundancy HARQ scheme based on parallel concatenated LDPC codes, the throughput performance of this program is given closed-form solution. In AwGN channel and Rayleigh fading channels through simulation, the performance of the performance of the new program and random LDPC codes are compared. The results show that the parallel concatenated LDPC codes incremental redundancy HARQ scheme performance close to the random LDPc code, but compiled more simple decoding a wider range of parameter selection.)
