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.)

ATMEGA8_ LTC2400 6位半表头程序 LTC2400最高测量电压为5.3V，超过5.3V或反接都会烧掉。 模拟部分供电最好经过7815稳压，最高输入电压不宜超过18V。 模拟电路与数字电路分开供电。 不要使用开关电源或PWM升压、降压电路供电 (ATMEGA8_ LTC2400 6 ½ -digit meter program LTC2400 highest measured voltage is 5.3V, 5.3V or reverse will be burned over. After 7815 some of the best analog power supply voltage, the maximum input voltage should not exceed 18V. Separate analog and digital circuit power supply. Do not use a switching power supply or PWM buck, boost circuitry)
