详细讲述了直接序列扩频差分锁相环的文章，包含具体的算法结构，并附有仿真结果。(A novel differentially coherent delay-locked loop(DCDLL) for accurate code tracking is proposed for direct sequence spread spectrum systems. Due to the use of the differential decoder and exactly one correlator, the proposed scheme avoids the problems of gain imbalance. The tracking error variance is derived by linear analysis. When the proposed DCDLL scheme is applied in ranging with additive white Gaussian noise (AWGN) channel, the performance of the proposed DCDLL scheme is about 1.4 dB better than that of one-correlator tau–dither loop (TDL), and near that of noncoherent DLL.)

buck convertor and two-loop control

This package contains Matlab class to serialize/decode matlab object in json format. The software uses org.json java package to convert json to java object and then translates it into Matlab object.

这是一个去马赛克工具软件，对实现图像分析和数码相机开发有着重要的价值．(This is a mosaic tools to software, the realization of image analysis and the development of digital cameras has an important value.)

说明：  fdtd 例程，了了解和学习FDTD方法的基础，呵呵，很不错的哦(fdtd routines, understanding and learning based on the FDTD method, huh, oh very good)
