书籍 Wireless Optical Communication Systems
The use of optical free-space emissions to provide indoor wireless commu-
nications has been studied extensively since the pioneering work of Gfeller
and Bapst in 1979 [1]. These studies have been invariably interdisciplinary in-
volving such far flung areas such as optics design‚ indoor propagatio ...
模拟电子 了解模数转换器的噪声、ENOB
Abstract: Specifications such as noise, effective number of bits (ENOB), effective resolution, and noise-free resolution inlarge part define how accurate an ADC really is. Consequently, understanding the performance metrics related to noise isone of the most difficult aspects of transitioning from ...

Windows CE This code detects memory leaks in embedded VC++ almost the same way crtdbg does in VC++. At the end
This code detects memory leaks in embedded VC++ almost the same way crtdbg does in VC++. At the end of program execution it will display in the debug window if there were any memory leaks and how the memory looks so you can identify where your memory leak occurred. It will display in the debug windo ...
技术资料 基于DSP的256PPM调制设计
· 摘要：  FSO (Free space optical)光线光通信结合了无线通信和光纤通信的优点,其关键技术在于收发端机的研制;PPM(PulsePosition Modulation)脉冲位置调制具有低的平均功率和较高的峰值功率,特别适合于无线光通信.该文根据PPM调制信号的特点和DSP技术,提出了一种用DSP实现256PPM调制的方案,整个方案有较大的灵 ...
