论文 Large-scale+Antenna+Systems
To meet the future demand for huge traffic volume of wireless data service, the research on the fifth generation
(5G) mobile communication systems has been undertaken in recent years. It is expected that the spectral and energy
efficiencies in 5G mobile communication systems should be ten-fold highe ...

学术论文 基于DSP的永磁同步电机新型矢量控制技术研究.rar
应用于电动汽车驱动领域的永磁同步电机交流驱动系统是由永磁同步电机、电力电子技术和控制技术相结合而形成的新型交流驱动系统。因其具有良好的运行性能而成为当代电气传动领域研究的热点之一。 永磁同步电机是一个多变量、非线性、高强耦合的系统,其输出转矩与定子电流不成正比,而是复杂的函数关系,因此要得到好的控制 ...
学术论文 基于FPGA的磁盘阵列控制器的硬件设计与实现.rar
随着存储技术的迅速发展,存储业务需求的不断增长,独立的磁盘冗余阵列可利用多个磁盘并行存取提高存储系统的性能。磁盘阵列技术采用硬件和软件两种方式实现,软件RAID(Redundant Array of Independent Disks)主要利用操作系统提供的软件实现磁盘冗余阵列功能,对系统资源利用率高,节省成本。硬件RAID将大部分RAID功能集 ...
学术论文 一种基于SIFT描述子的特征匹配新算法
为了克服传统的局部特征匹配算法对噪声和图像灰度非线性变换敏感的不足,提出了基于SIFT(Scale Invariant Feature Transform)描述算子的特征匹配算法。该算法首先
模拟电子 基准电压的温度漂移研究应用笔记
Abstract: A perfect voltage reference produces a stable voltage independent of any external factors. Real-world voltagereferences, of course, are subject to errors caused by many external factors. One causeof these major errors istemperature. Without care, it is easy to operate a voltage reference ...
模拟电子 精密DAC和看门狗提高模拟输出安全
Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and data-acquisition systems. The analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failure, optocoupler fail ...
模拟电子 视频差分放大器带来低电压应用的多功能性
 
The LT®6552 is a specialized dual-differencing 75MHzoperational amplifier ideal for rejecting common modenoise as a video line receiver. The input pairs are designedto operate with equal but opposite large-signal differencesand provide exceptional high frequency commonmode rejection ( ...
模拟电子 DN426 6通道工业监控应用的SAR ADC
 
The 14-bit LTC2351-14 is a 1.5Msps, low power SARADC with six simultaneously sampled differential inputchannels. It operates from a single 3V supply and featuressix independent sample-and-hold amplifi ers and a singleADC. The single ADC with multiple S/HAs enables excellentrange match (1m ...
