A digital filter structure for wideband filtering is proposed. It consists of two allpass filters and a linearphase FIR filter. One major advantage of this structure is that the allpass filters are functions of zM which implies that the maximal sample frequency is M times higher for this structure than for the corresponding conventional structures.

Some time ago, I stated in another article that I d take the idea of location broadcasting and develop a mobile solution as a follow-up. The problem back then was I had no means to get location data off of a cell phone, or a way to make it useful. My, how times have changed since then! In this article, I ll demonstrate how to get your phone s GPS coordinates…

Consider a BPSK and a QPSK system for the following two cases: 1) The probability that the symbol 1 is sent and the probability that the symbol 0 is sent are all the same. 2) The probability that the symbol 1 is sent is two times than the probability that the symbol 0 is sent. Assume that the noise is Gaussian distributed with mean=0 and 2 = 1.

C++ is a programming language. It is a programming language of many different dialects, just like each language that is spoken has many dialects. In C though, they are not because the "speakers" live in the North, South, or grew up in some other place, it is because there are so many compilers. There are about four major ones: Borland C++, Microsoft Visual C++, Watcom C/386, and DJGPP. You can download DJGPP http://www.delorie.com/djgpp/ or you may already have another compiler. Each of these compilers is a little different. The library functions of one will have all of the standard C++ functions, but they will also have other functions or, continuing the analogy, words. At times, this can lead to confusion, as certain programs will only run under certain compilers, though I do not believe this to be the case with the programs in these tutorials.

Behavioral models are used in games and computer graphics for realistic simulation of massive crowds. In this paper, we present a GPU based implementation of Reynolds [1987] algorithm for simulating flocks of birds and propose an extension to consider environment self occlusion. We performed several experiments and the results showed that the proposed approach runs up to three times faster than the original algorithm when simulating high density crowds, without compromising significantly the original crowd behavior.

Quartus II 11.0的安装使用指南，从Quartus II 5.0开始使用，几年时间软件版本增长较快，中间若干版本还没来得及体验，现已是12.0版。不过对于软件核心构架而言，万变不离其宗，不一定要追求最新。从使用体会来说，11.0版还不错。下面介绍其安装和使用。

电流跟踪型逆变器输出电流跟随给定的电流波形变化，这也是一种PWM控制方式。电流跟踪一般都采用滞环控制，即当逆变器输出电流与给定电流的偏差超过一定值时，改变逆变器的开关状态，使逆变器输出电流增加或减小，将输出电流与给定电流的偏差控制在一定范围内。
