UWB _sv_*. m : Four M-files used to generate channel impulse r esponses (MAT files).

基于MODBUS规约的双向通讯程序，串口通讯-MODBUS-based two-way communication procedures of the Statute, serial communication

用在32位计算机上的串口通信打包接口库文件.前面的各种结构体,除了因为字宽原因, 使用了不同数据类型以外,实际效果与相应的单片机程序接口是一致的.平台独立.-with 32 computers in the serial communication interface library package. In front of the structure, in addition to the reasons for wide characters, the use of different data types, the actual results with the corresponding microcontroller interface is the same. Platform independence.

这是一非常好的CMMB教材，PPT的格式。里面涉及到了关键信道编码技术和调制技术。讲得很详细。对初学CMMB的人来说很有意义哦。-This is a very good CMMB materials, PPT format. Which relates to a key channel coding techniques and modulation techniques. Very detailed. For beginners who CMMB Oh meaningful.
