基于matlab的QPSK调制与解调程序(QPSK modulation and demodulation)

作为TCP客户端跟TCP服务端进行通讯，支持modbus协议(As a TCP client to communicate with the TCP server to support the modbus protocol)

说明：  MATLAB代码，产生GNSS导航信号BOC调制的相关频谱特性(The generate of BOC signal AND ITS PDF)

说明：  MANET routing model with DSR

ML python library scratch

802.16E的协议文档，完整版本。其中包括3个版本。(802.16E protocol document, full version.)

BTicino的网关通讯协议详细说明,非常详细,看完了就可以自己动手控制BT智能家居了!(BTicino gateway protocol details, very detailed, have read to make your own intelligent home control it!)

Factorial recursion , try it

说明：  该软件的处理类似于短时傅立叶变换（STFT），但应用了更长、更重叠的分析/合成窗口，使时频处理从根本上对混叠具有鲁棒性。这种差异与非常活跃的时频处理技术有关，例如Dirac或优化的自适应波束形成器。(The software does processing similar to the short-time Fourier transform , but applies the longer and more overlapping analysis/synthesis window to make the time-frequency processing fundamentally robust for aliasing.)

完整的射频门禁程序源码包含rc522的驱动程序以及相应的显示程序(There had been many cases about RFID-based access control systems. In this paper, long-distance radio frequency technology was used and image-recognition technology was joined, these technologies were used to realize the automation of access management.)
