利用通讯模块进行数据通信，就是将数据体作为短消息的内容，从发送方的通讯模块发送出去，通过短消息中心进行转发，接收方通讯模块收到此短消息后即存储在SIM卡上，模块外接的控制器（如单片机、计算机等）从模块中读取短消息后，根据需要将无用的信息去除，取出有效信息，然后将SIM卡中的短消息删除，这样就完成一次单向数据的传输。利用通讯模块的短消息方式实现数据的发送和接收具有通信成本低、系统容量大、抗干扰能力强等优点，而且短消息经过服务中心再到达目的地的特点使通讯模块无需24小时开机，降低了系统功耗，特别适合遥控、遥测、远程信息处理和通信等领域。

This simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data.

ALTERA Nios II Embedded Evaluation Kit开发板制造商(terasic)提供的多媒体显示板（Terasic Multimedia Touch Panel Daughter Board (MTDB)）扩展开发包。 里为有两个开源的例子 1.MTDB_SD_Card_Audio,从SD卡中读取WAV文件然后通过DA播放，这个对不SD Card的初学者非常的有用，可以知道使用FPGA SPI来读写SD CARD。 2.MTDB_Systhesizer,使用FPGA来做电子琴，要用FPGA来做合成器的看这个。 国内部分地区的网络对TERASIC封杀，原因不明，这个包是使用代理下载的，非常不容易。
