ofdm-modulation

TDOA算法包括泰勒，最小二乘法，chan算法及改进算法等(TDOA algorithm includes Taylor, least square method, Chan algorithm and improved algorithm)

说明：  GPS串口通信程序，新建了一个数据库ACCESS，在显示当前GPS信息的同时可以存储以前记录过的信息，保存在数据库中，便于以后查阅。当前GPS信息包括：时间，经度，纬度，速度，真实航向以及磁偏移(GPS serial port communication program, a database of new ACCESS, show the current GPS information can be stored at the same time the information previously recorded, stored in a database for easy access later. The current GPS information including: time, longitude, latitude, speed, true course and magnetic offset)

Modbus协议及Modbus RTU的C51编程(Modbus RTU Modbus protocol and the C51 programming)

通信中利用匹配滤波，产生斜坡信号，并进行相应滤波(Communication using matched filtering, resulting in ramp, and the corresponding filter)

这是16QAM的仿真，带GUI界面，很好用的。(This is 16QAM simulation, with GUI interface, very useful.)

智能语音小车标准程序，已经测试通过了的。完全没有问题。(The standard program of intelligent voice car has passed the test. No problem at all.)
