In recent years large scientific interest has been devoted to joint data decoding and parameter estimation techniques. In this paper, iterative turbo decoding joint to channel frequency and phase estimation is proposed. The phase and frequency estimator is embedded into the structure of the turbo de ...

Carrier-phase synchronization can be approached in a general manner by estimating the multiplicative distortion (MD) to which a baseband received signal in an RF or coherent optical transmission system is subjected. This paper presents a unified modeling and estimation of the MD in finite-alphabet d ...

Anyone who interacts with today s modern databases needs to know SQL (Structured Query Language), the standard language for generating, manipulating, and retrieving database information. In recent years, the dramatic rise in the popularity of relational databases and multi-user databases has fueled ...

The need for accurate monitoring and analysis of sequential data arises in many scientic, industrial and nancial problems. Although the Kalman lter is effective in the linear-Gaussian case, new methods of dealing with sequential data are required with non-standard models. Recently, there has been re ...

This zip file describes how to generate a clock on the PCK pin using the PMC running under AT91RM3400DK with Green hills 3.6.1 Multi&reg 2000 Software Tool. Includes main.html file for help.

To estimate the input-output mapping with inputs x ％ and outputs y generated by the following nonlinear, ％ nonstationary state space model: ％ x(t+1) = 0.5x(t) + [25x(t)]/[(1+x(t))^(2)] ％ + 8cos(1.2t) + process noise ％ y(t) = x(t)^(2) / 20 + 6 squareWave(0.05(t-1)) + 3 ％ + time varying measur ...

这是一个学习WinSocket编程的程序，它由3部分组成，一是发送Sender的程序，另一个是接收Receiver的程序，还有一个是信道channel。发送方发送的数据需要经过信道才能够被接收方接收到。这个信道是一个模拟信道，可以自由设置它成为可靠或者不可靠，在不可靠时又有几种情况。这些都是为了能够更好地去理解数据链路层的编程， ...

This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).

这是我自己写的用于嵌入式设备的CGI程序，ANSI C编写，嵌入式Linux中使用。这些CGI代码是我在CGIC库的基础上加上了常用的一些外围功能模块函数，比如读写配置文件等。其中比较重要的是我自己实现的session控制、页面模板方式（模板标签替换）和web多语言版本的一种我自己的实现方法。请参阅cgi_functions.c、session.c和mul ...

A new cable fault location method based on wavelet reconstruction is proposed. In this method the difference between the currents of faulty phase and sound phase under the high voltage pulse excitation is used as the measured signal and is decomposed in multi-scale by wavelet transform, then reconst ...
