NAME: u2440mon.c DESC: u2440mon entry point,menu,download HISTORY: Mar.25.2002:purnnamu: S3C2400X profile.c is ported for S3C2410X. Mar.27.2002:purnnamu: DMA is enabled. Apr.01.2002:purnnamu: isDownloadReady flag is added. Apr.10.2002:purnnamu: - Selecting menu is available in the waiting loop. So, isDownloadReady flag gets not needed - UART ch.1 can be selected for the console. Aug.20.2002:purnnamu: revision number change 0.2 -> R1.1 Sep.03.2002:purnnamu: To remove the power noise in the USB signal, the unused CLKOUT0,1 is disabled.

1、提取原蛋白質(zhì)相互作用網(wǎng)絡的所有節(jié)點 2、分別計算原蛋白質(zhì)相互作用網(wǎng)絡每個節(jié)點的度 3、從所有節(jié)點中選擇具有最高度的節(jié)點，反復的添加邊，直到它的度值等于原蛋白質(zhì)相互作用網(wǎng)絡該節(jié)點的度值 4、在為節(jié)點添加邊時，從剩余節(jié)點中選擇節(jié)點的方法是其度分布近似服從power-low分布 5、令t的值為零，則每個節(jié)點被選到的可能性都是相同的，由于在原蛋白質(zhì)相互作用網(wǎng)絡存在大量的低度節(jié)點，所以集散節(jié)點會優(yōu)先連接低度節(jié)點。 這樣創(chuàng)建的網(wǎng)絡就為負相關蛋白質(zhì)互作網(wǎng)絡

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.

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

用fpga實現(xiàn)的DA轉(zhuǎn)換器，有說明和源碼，VDHL文件。 A PLD Based Delta-Sigma DAC Delta-Sigma modulation is the simple, yet powerful, technique responsible for the extraordinary performance and low cost of today s audio CD players. The simplest Delta-Sigma DAC consists of a Delta-Sigma modulator and a one bit DAC. Since, both of these components can be realized using digital circuits, it is possible to implement a low precision Delta-Sigma DAC using a PLD.

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
