代码说明:

  数字调制技术的发展日新月异现如今信息技术不断的推陈出新,信息的传输及通信起着支撑作用。而对于信息的传输,数字通信已经成为重要的手段。因此,数字信号的调制就显得非常重要。数字调制是通信系统中最为重要的环节之一,而实现数字调制需要的方法就需要用键控法来实现,比如可以对载波的振幅、频率和相位进行键控。(ASK , FSK , PSK modulation and demodulation of the simulation comparison )

    基于matlab的OFDM仿真程序; 我再论坛找了很多OFDM的代码和文章,但总有遗患,为什么呢原因是大部分只有简单的映射,IDFTDFT变换等等,但主要的同步和信道估计去没有人提出来,甚至做出来.. 现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFTDFT,同步(时间频率同步)和信道估计,以及频率偏移的估计等一系列代码.(Based on the OFDM matlab simulation program I' ll find a lot of forums and articles OFDM code, but there are left suffering, why because most only simple mapping, IDFTDFT transformation, etc., but the main synchronization and channel estimation to no one proposed, and even do it .. and now I finally found a copy of it in the form FUNCTION, Reproduction of OFDM mapping, IDFTDFT, synchronous (time and frequency synchronization) and channel estimation, and the estimated frequency offset a series of code.)

    说明:   该电路由一片四双向模拟开关集成电路CD4066为核心构成。每个电路内部有四个独立的能控制数字或模拟信号传送的开关。当水箱无水时,由于180K电阻的作用,使四个开关的控制端为低电平,开关断开,LED 不发光。随着水位的增加, 由于水的导电特性,使得IC的13脚为高电平,S1接通,LED1点亮。当水位逐渐增加时,LED依次发光指示水位。水满时, LED4发光, 显示水满。同时T1导通, B发出报警声,提示水已满。不需要报警声时,断开开关K即可。 (The circuit consists of a four-way analog switch integrated circuit CD4066 core composition. Within each circuit to control four separate digital or analog signal transmission in the switch. When the tank water, the role of the 180K resistor, so that the four low-side switch control, switch off, LED does not light. As the water level increases, the electrical properties of water, making the IC' s 13 feet high, S1 connected to, LED1 lights up. When the water level gradually increased, LED turn light level indication. Is full of water, LED4 LED display full of water. At the same time conducting T1, B alarm will sound, indicating that the water is full. Do not need to sound the alarm when the disconnect switch K can be.)
