Device-to-device(D2D) communications are now considered as an integral part of future 5G networks which will enable direct communication between user equipment (UE) without unnecessary routing via the network infrastructure. This architecture will result in higher throughputs than conventional cellular networks, but with the increased potential for co-channel interference induced by randomly located cellular and D2D UEs.

The challenges associated with the design and implementation of Electro- static Discharge (ESD) protection circuits become increasingly complex as technology is scaled well into nano-metric regime. One must understand the behavior of semiconductor devices under very high current densities, high temperature transients in order to surmount the nano-meter ESD challenge. As a consequence, the quest for suitable ESD solution in a given technology must start from the device level. Traditional approaches of ESD design may not be adequate as the ESD damages occur at successively lower voltages in nano-metric dimensions.

The continuous progress in modern power device technology is increasingly supported by power-specific modeling methodologies and dedicated simulation tools. These enable the detailed analysis of operational principles on the the device and on the system level; in particular, they allow the designer to perform trade- off studies by investigating the operation of competing design variants in a very early stage of the development process. Furthermore, using predictive computer simulation makes it possible to analyze the device and system behavior not only under regularoperatingconditions, but also at the rim of the safe-operatingarea and beyond of it, where destructive processes occur that limit the lifetime of a power system.

随着图像处理技术的不断发展，图像处理技术在国民经济和社会生活的各个方面都得到了广泛的运用。与此同时，人们对图像处理的要求也越来越高。传统的数字图像处理器件主要有专用集成芯片（Application Specific Integrated Circuit）和数字信号处理器（Digital Signal Process）。进入20世纪以来，伴随着半导体技术的发展，现场可编程门阵列FPGA以其应用灵活、集成度高、功能强大、设计周期短、开发成本低的特点，越来越多地被应用在图像处理领域。大量实践证明，FPGA的并行处理能力与流水线作业能显著地提高图像处理的速度，因此基于FPGA的图像处理系统有着广阔的发展前景。 本文研究的是一个在嵌入式视频监控系统下的图像预处理子系统。首先实现了一个通用可重复配置的图像处理算法研究硬件平台，完成图像的采集、接收、处理、存储、输出等功能。由于FPGA本身具有完全的可重复配置性，所以该架构的硬件平台可以很方便的升级和重复配置。其次在该平台上，本文使用Verilog HDL硬件语言在FPGA芯片上实现了多种图像预处理算法。在实现过程中，为了充分发挥FPGA在并行处理方面的强大功能，本文对算法做了一定的改进，使其尽量能使用并行处理的方式来完成。实验结果表明，本图像预处理系统能在毫秒级高速地完成多种图像算法，完全能够满足视频监控系统50帧/秒的输出要求。 最后根据视频监控系统在实际运用中出现的噪声类型多样化的情况，我们设计了一种基于反馈理论的图像处理效果控制模块。该模块能通过对处理后图像峰值信噪比（PSNR）的分析，控制FPGA对下一幅图像的噪声采用更有针对性的图像处理方法。
