接地技术最早是应用在强电系统（电力系统、输变电设备、电气设备）中，为了设备和人身的安全，将接地线直接接在大地上。由于大地的电容非常大，一般情况下可以将大地的电位视为零电位。后来，接地技术延伸应用到弱电系统中。对于电力电子设备将接地线直接接在大地上或者接在一个作为参考电位的导体上，当电流通过该参考电位时，不应产生电压降。然而由于不合理的接地，反而会引入了电磁干扰，比如共地线干扰、地环路干扰等，从而导致电力电子设备工作不正常。可见，接地技术是电力电子设备电磁兼容技术的重要内容之一，有必要对接地技术进行详细探讨。(Grounding technology was first applied in strong electric system (power system, power transmission equipment, electrical equipment), in order to equipment and personal safety, the ground wire directly connected to the earth. Because the earth capacitance is very large, under normal circumstances can be considered to be zero potential earth potential. Later, grounding techniques applied to extend the weak system. For power electronic devices directly connected to the ground wire on the ground or connected to a reference potential as a conductor, when the current through the reference potential, and should not generate voltage drop. However, due to unreasonable ground, but will the introduction of electromagnetic interference, such as co-ground interference, ground loop interference, resulting in power electronic equipment is not working properly. Visible, grounding technology is an important part of power electronic equipment EMC technology, it is necessary for grounding techniques disc)

LDPC码编译码算法的研究与实现_李会雅
本文首先介绍了几种LDPC码的编译码算法，同时推导了译码错误概率和密度进化
过程，讨论了信道参数的门限效应。接着对LDPC码二分图中长度为4的环进行了深入
研究，提出了一种LDPC码校验矩阵的消4一环生成算法，采用Matlab和VC++融合编程
方式，完成了此算法的程序设计。此算法不仅可生成二进制LDPC码的校验矩阵，并且
对算法修正后，也可生成多进制LDPC码的校验矩阵。采用此算法后可避免LDPC码译
码过程中的重复迭代，显著提高了短帧LDPC码的误比特率性能。同时对不同参数对
LDPC码性能的影响进行了仿真，得到了一些结论。最后，利用VHDL语言在复杂可编
程逻辑器件(CPLD)上完成了LDPC码编码器的硬件实现。另外，给出了LDPC码译
码器硬件实现的整体结构图，结合对数似然比域内的置信传播迭代译码(LLR-BP)算
法，对译码器的各个模块进行了详细阐述。(Research and implementation of LDPC coding and decoding technology)
