用同步理论实现缓存通信：Producer发送0-200到Buffer，同时Buffer发送到Consumer-Cache implementation using synchronous communication theory: Producer Send 0-200 to Buffer, meanwhile Buffer sent to the Consumer

GPRS通信程序，可发送数据，并获得GPRS设备的信息。-GPRS communication program can send data, and access to GPRS devices.

介绍了用visual c++编写应用程序调用api函数，从而简化了与硬件通信的过程。-introduces the visual c write applications called api function, thus simplifying the hardware and communications process.

我们自己创建各个的头部,系统只是把它们发送出去. 在实例中,由于我们要修改我们的源IP地址, 所以我们使用了setsockopt函数,如果我们只是修改TCP数据,那么IP数据一样也可以由系统来创建的. -To create all our own head, the system only to send them out. In the example, because we have to modify our source IP address, so we use the setsockopt function, if we just amend the TCP data, then the IP can also be from the same data system to create the.

此程序参照了IEEE 802.11a ，使用了52个子载波。理论期望papr为52.但是由加扰器的存在，所有子载波很难一直的调制-Per the IEEE 802.11a specifications, we 52 have used subcarriers. Given so, the theoretical maximum expected PAPR is 52 (around 17dB). However, thanks to the scrambler, all the subcarriers in an OFDM symbol being equally modulated is unlikely.
