串行通信(还是与移动的GPRS有关,只是界面比较美观)-serial communications (or with the GPRS mobile, but more attractive interface)

使用Com口、Modem进行通讯的控件，自己做的。-I use Com, Modem communications for the controls themselves do.

专业的串口程序开发包（非源码），非常方便-professional procedures Serial Development Kit (FOSS), a very convenient

介绍了一种构建在定点DSP上的高速瑞利衰落信道仿真模型。通过应用确知性瑞利过程的理论，使得仅需要较少的低频正弦波分量以及简单的运算即可实现较高精度的信道建模；进而可采用查表法并结合TMS320C6202定点数字信号处理器的高并行性和处理能力构造高速的仿真模型-Construction of a fixed-point DSP in the high-speed Rayleigh fading channel simulation model. Through the application process unascertained Rayleigh theory, only need to make small low-frequency sine wave components and the simple operation can achieve higher accuracy Channel modeling; then use look-up table method and combination TMS320C6202 fixed-point digital signal processor parallel and can handle Construction of the high-speed simulation model
