本文講述了一個基於FAN4800 連續PFC 前端的雙管正激電源的功率級設計。回顧了這種電源的設計選擇。討論的實際課題包括功 率器件選型，電磁設計，佈局和電磁干擾 (EMI)，目的在於幫助工程師加速並改善其設計。(This article about a front-end based on the FAN4800 PFC consecutive two-transistor forward power stage power supply design. Review this power supply design options. The actual topics discussed include the selection of power devices, electromagnetic design, layout, and electromagnetic interference (EMI), designed to help engineers to speed up and improve its design.)

gps跟踪中的伪码相位，很好用的，可以下载下来(pncode——track)

说明：  本程序实现了短数据序列不同窗函数的welch功率谱估计，然后又求了他们的平均标准差，从而判断各个窗函数的优劣。只要稍作修改就能实现不同信噪比下的功率估计，同时也可以实现长数据序列的估计。(This procedure has a short data series of different welch window function power spectrum estimation, and then seek their average standard deviation, and thus to determine the merits and demerits of each window function. As long as we can with some slight modifications under different signal to noise ratio power estimate, but also the realization of a long data sequence can be estimated.)

我看到网上很多雷达信号处理的人都想从IPIX网站上下载数据，可是却没有MexCDF toolbox ，今天我把它上载，百分之白能用，里面有详细的安装步骤，可以在matlab7到matlab2012上使用。(I see online many radar signal processing wants to download data from the IPIX website, but did not MexCDF toolbox I upload per cent of white can be used, which has detailed installation steps, in matlab7 to matlab2012 to use.)
