This demonstration illustrates the application of adaptive filters to signal separation using a structure called an adaptive line enhancer (ALE). In adaptive line enhancement, a measured signal x(n) contains two signals, an unknown signal of interest v(n), and a nearly-periodic noise signal eta(n). The goal is to remove the noise signal from the measured signal to obtain the signal of interest.

MATFOR FFT Visual Fortran program. MATFOR Extensions, as implied in the name, are data or components external to MATFOR modules that can be used to add versatility to MATFOR programs. Currently there are two types of extensions available with MATFOR, they are MATLAB Interface and Tecplot FileIO. MATLAB Interface, a new feature in MATFOR 4.1, provides MATFOR users access to MATLAB functions so they can obtain functionality that has not been built into MATFOR. The ability of using MATLAB functions makes MATFOR an ideal tool for those who create prototypes using MATLAB, then do implementation in C++ and other programming languages. Through the use of MATFOR, users may perform quick results comparisons between MATLAB and other languages.

Abstract-The effect of the companding process on QAM signals has been under investigation for the past several years. The compander, included in the PCM telephone network to improve voice performance, has an unusual affect on digital QAM data signals which are transmitted over the same channel. The quantization noise, generated by the companding process which is multiplicative (and asymmetric), degrades the detectability performance of the outermost points of the QAM constellation more than that of the inner points. The combined effect of the companding noise and the inherent white gaussian noise of the system, leads us to a re-examination of signal constellation design. In this paper we investigate the detectability performance of a number of candidates for signal constellations including, a typical rectangular QAM constellation, the same constellation with the addition of a smear-desmear operation, and two new improved QAM constellation designs with two-dimensional warpi

Description 為了宣傳本次“網宿科技杯”廈門大學第五屆程序設計競賽，系里面做了兩張精美的海報。經過了精確的計算，為了達到最佳美觀效果，每張海報都有自己最佳的粘貼位置。但是現在問題是，如果兩張海報都要求貼在最佳位置時，很有可能有部分地方會重疊在一起。現在您來判斷一下這兩張海報是否重疊。 Input 輸入包含兩行，每一行有四個整數來描述這個海報的最佳粘貼位置，X,Y,W,H(-10000<= X,Y <= 10000)(0 < W, H <= 10000)，X,Y表示海報左下角的坐標，W,H分別表示寬度和高度。 Output 輸出"Yes"表示兩張海報互相重疊(表示存在一個面積大于0的公共區域)，否則輸出"No"。(不包含引號，注意大小寫) Sample Input -10 -10 20 30 0 0 30 20 Sample Output Yes
