WCDMA系统中RAKE接收机路径搜索算法的改进的研究
<p>RAKE接收机在时域最优联合多径，在提供严格的功率控制下可以克服多径衰落，提高信道容量，因此是 code-division multiple access（CDMA）扩频通信的关键技术之一。本文围绕RAKE接收机在 wide-band code-division multiple access（WCMA》系统中的应用，重点研究了RAKE接收机中的信道参数估计和路径搜素技术，并提出了一种新的接
用于产生瞬态等离子体的脉冲电源的设计
<p>为了更好的进行瞬态等离子体机理的研究,瞬态等离子体的产生是其实验研究的关键,为此设计一台可调节高压方波脉冲电源。该脉冲电源主要有高压直流电源和固态调制器组成,电压调节主要由直流电源完成,固态调制器是基于单片机为控制中心,信号经过隔离和功率放大,实现固态调制器的控制,由于输出电压较高,单个开关管无法承受耐压,所以采用MOSFET串联分压的方式。</p><p>In order to study
