- OpenSource GPS is software for x86 PCs that allows you to acquire, track and demodulate signals from GPS satellites. OSGPS requires a Zarlink GP2021 12 channel GPS correlator chip
QPSK.rar
- QPSK是一种二维调制技术，其中水平轴称为同相轴，垂直轴称为正交轴，分别对应于星座图上的1和Q坐标。同相载波指载波本身，正交载波指相位旋转90度的载波1周。QPSK调制在实现时是采用正交调幅的方式，某星座点在1坐标上的投影去调制同相载波的幅度，在Q坐标上的投影去调制正交载波的幅度，然后将两个调幅信号相加就是所需的调相信号,QPSK is one kind of two-dimensional modulating technology, the horizontal axis is called

RFIDreceiver
- 对RFID读写器接收模块的解调以及FM0解码进行了MATLAB仿真。首先我们对读写器接收到的信号进行仿真，里面附带着标签信息；其次对接收到的ASK信号进行相干解调；接着解调后的信号经过抽样判决，进行FM0解码。仿真结果可表明接收到的信号与发射的信号一致。-On the RFID reader receiver module FM0 decoding and demodulation and a MATLAB simulation. First of all we readers received
