Description: 调试环境以及需要安装的软件和硬件
本程序在Windows XP、Visual C++6.0版本环境下编译通过。需要rtcdll.dll文件（此文件一般在Windows安装目录下的system32文件夹中）。
另外，MMSYSTEM.H头文件一般在“C:\Program Files\Microsoft Visual Studio\VC98 \Include”目录下（请读者按照自己安装VC++的目录查找）。如果不是完全安装VC++，可能没有这个文件，可在本章源代码光盘中找到该文件。
运行程序需要摄像头和麦克风等设备。-Debugging environment and the need to install the software and hardware of this procedure in Windows XP, Visual C++ 6.0 version of the compiler through the environment. Need Rtcdll.dll file (this file is normally installed in the Windows directory under the system32 folder). In addition, MMSYSTEM.H header file is normally C: Program FilesMicrosoft Visual StudioVC98 Include directory (please readers installed according to its own VC++ Directory to find). If it is not completely installed VC++, May not have this document, the source code in this chapter can be found in the paper disc. Need to run the program, such as camera and microphone equipment.

Description: This project aim was to build wireless software modem for data communication
between two computers using an acoustic interface in the voice frequency range (20Hz–
20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz –
20,000Hz) and the receiving antenna is a microphone (frequency response of: 100Hz –
16,000Hz). The test files used as information files were text files.
This goal was attained both in an incoherent scheme and in a coherent scheme.
Build under Matlab code, our modem uses OFDM (orthogonal frequency division
multiplexing) modulation, synchronization by LMS sequence, channel estimation (no
equalizer) via pilot tones. The symbols are either PSK or ASK for a constellation size of
2 or 4. To optimize the probability of error, these symbols were mapped using Gray
mapping.
