PWM-ULN2003A
利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h>
unsigned char timer1
sbit PWM=P1^2
void system_Ini()
{
TMOD|= 0x11
//PWM
TH1 = 0xfe //11.0592
TL1 = 0x33
TR1 = 1
IE =0x8A
}
main()
{
system_Ini()
while(1)
{ if(timer1>100) timer1=0
if(timer1<30) PWM=0
else PWM=1
}
)

无线信道时延扩展仿真
无线信道时延扩展仿真
一、仿真目的
在数字通信中，无线信道所表现出的时延扩展将有可能引起接收信号的码间串扰。实验的目的是从时域角度方面对移动信道的多径环境引起的接收信号时延扩展现象进行仿真。(wireless channel delay spread simulation
One, the simulation purpose
In digital communication, wireless channel delay spread shown will likely cause the received signal crosstalk code. The aim of the experiment is to delay the received signal due to multipath environment of mobile channel in time domain and the phenomenon of simulation.)

PPM_PCM_FM_2.4G
2.4g和FM（72MHZ，40MHZ，35MHZ……）是个啥信号波，就是我们的控制内容，手拿遥控器推一推摇杆，信号波的频率就会改变(2.4g and FM (72MHZ, 40MHZ, 35MHZ ......) is Gesha signal wave is our control content, holding the remote control push, rocker, will change the frequency of the signal wave)
