QPSK调制全称Quadrature Phase Shift Keying ,意为正交相移键控，是一种数字调制方式。数字信号的四相相移键控调制与解调技术以其灵活性和通用性而得到广泛的应用，符合未来数字通信技术发展的方向。随着移动通信技术的发展，以前在数字通信系统中采用FSK、ASK、PSK等调制方式，逐渐被许多优秀的调制技术所替代。(QPSK modulation partial Quadrature Phase Shift Keying, Quadrature Phase Shift Keying means, is a digital modulation. Digital signal quadrature phase shift keying modulation and demodulation technology for its flexibility and versatility which has been widely used, in line with the future direction of development of digital communication technologies. With the development of mobile communication technology, previously used in digital communication systems FSK, ASK, PSK modulation, etc., many excellent modulation gradually being replaced by technology.)

simulink single phase matrix converter. Very easy to understand and run well

FDTD仿真，空气和玻璃界面的折射现象，可以观察到电磁波的折射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor. )
