研制了一種基于DDC 芯片的直接中頻數(shù)字化雷達(dá)正交接收機(jī),分析了I/ Q 通道的增益誤差和正交誤差對解調(diào)輸出信號的影響。結(jié)果表明,設(shè)計的接收機(jī)通道間誤差對解調(diào)輸出的影響完全可以忽略。最后對接收機(jī)性能進(jìn)行了測試,得到了理想的解調(diào)結(jié)果

mkdosfs - Make DOS file system utilty. I wrote this, partially to complement the dosfsck utility written by Werner Almesberger (who graciously gave me some pointers when I asked for some advice about writing this code), and also to avoid me having to boot DOS just to create data partitions (I use Linux to back up DOS :-) ).

Last week I posted an article on a simple C++ template class, XYDataArray, I used in my system development tool. The main purpose of this template class is to store and sort general data types. I needed to implement the same thing in Java, since the tool I developed has a compatible Java version. I checked the Java SDK documentation before writing my own code, and found that almost everything I needed is already there, like the C++ case.

I always wanted to play around with JNI. This is my first attempt so I created a utility DLL called TestImpl.dll that exports several useful functions which are difficult or impossible to implement in JAVA.

What I am trying to introduce here is a full fledged Java Instant messenger, which has all the features supplied by commercial messengers like Yahoo or MSN. Although it cannot compared to be in par with those messengers, it is an attempt by me to learn Advanced Java and JNI concepts. The challenges I faced here were often overcome by referring to numerous sites, which nearly zeroes in or completely solved the issues I faced at that point of time. It improved my learning curve and also believe would do the same to you too. Ofcourse, there are some bugs and glitches, which I hope you would excuse. Thanks to anyone who takes the pain to report them or even suggest better way of doing things to me.
