书籍 Time-Varying Channels
Wireless communications has become a field of enormous scientific and economic interest. Recent
success stories include 2G and 3G cellular voice and data services (e.g., GSM and UMTS), wireless
local area networks (WiFi/IEEE 802.11x), wireless broadband access (WiMAX/IEEE 802.16x), and
digital broad ...
书籍 Cogeneration+and+District+Energy+Systems
District energy (DE) systems use central heating and/or cooling facilities to provide
heating and/or cooling services for communities. The advantages of district energy
over conventional heating and cooling include improved efficiency, reliability and
safety, reduced environmental impact, and for ma ...
书籍 Wide Area Monitoring, Protection
Today, electric power transmission systems should face many demanding chal-
lenges, which include balancing between reliability, economics, environmental,
and other social objectives to optimize the grid assets and satisfy the growing
electrical demand.
Moreover, the operational environment of trans ...
书籍 RFID AND SENSOR NETWORKS Architectures
Radio frequency identification (RFID) technology is witnessing a recent explosion of
development in both industry and academia. A number of applications include supply
chain management, electronic payments, RFID passports, environmental monitoring
and control, office access control, intelligent labe ...
书籍 A_Software-Defined_GPS_and_Galileo_Receiver
Software-defined radios (SDRs) have been around for more than a decade. The
first complete Global Positioning System (GPS) implementation was described
by Dennis Akos in 1997. Since then several research groups have presented their
contributions. We therefore find it timely to publish an up-to-date ...

源码 stdafx.h
--stdafx.h中没有函数库，只是定义了一些环境参数，使得编译出来的程序能在32位的操作系统环境下运行。
windows和mfc的include文件都非常大，即使有一个快速的处理程序，编译程序也要花费相当长的时间来完成工作。由于每个.cpp文件都包含相同的include文件，为每个.cpp文件都重复处理这些文件就显得很傻了。

技术资料 STM32F407VGT6精确脉冲控制步进电机源码
STM32F407VGT6精确脉冲控制步进电机源码,采用STM32F407VGT6芯片，抛弃单脉冲输出方式，直接使用普通PWM输出方式精确输出脉冲个数，每个脉冲都可以改变频率和占空比。PWM+中断，简单粗暴。#include "sys.h"#include "delay.h"#include "pwm1.h"#include "pwm2.h"#include "pwm3.h"//注释见pwm1.c文件extern int count2;int m ...
