空间矢量脉宽调制(Space Vector Pulse Width Modulation)  　　SVPWM的主要思想是:以三相对称正弦波电压供电时三相对称电动机定子理想磁链圆为参考标准，以三相逆变器不同开关模式作适当的切换，从而形成PWM波，以所形成的实际磁链矢量来追踪其准确磁链圆。传统的SPWM方法从电源的角度出发，以生成一个可调频调压的正 ...

自适应软频率复用技术在长期演进中上行上的应用，主要是如何解决小区边缘干扰问题。对小区边缘干扰提出了自适应软频率复用算法

color science; Provide a systematic introduction to the human vision system, color image formation, color reproduction, and color space.

Microprocessors  are  getting  smaller,  cheaper  and  faster.  Every  day,  it  is  easier to embed more functionality into a smaller space. Embedded processors have become pervasive, and as time goes on, more and more functions that were once ...

The 4.0 kbit/s speech codec described in this paper is based on a Frequency Domain Interpolative (FDI) coding technique, which belongs to the class of prototype waveform Interpolation (PWI) coding techniques. The codec also has an integrated voice activity detector (VAD) and a noise reduction capabi ...
