S259M
- This standard describes a serial digital interface for 525/60 and 625/50 digital television equipment operating with either 4:2:2 component signals or 4fsc composite digital signals. This standard has application in the television studio over
Design-of-UWB-diversity-antenna-for-PDA-applicati
- Two elements diversity planar antenna for a multiple-input multiple-output application is proposed. By adopting two Y-shaped radiators, the antenna provides wideband impedance matching characteristic over the desired frequency band. To reduce the
05441004
- Multiple input multiple output techniques combined with orthogonal frequency division multiplexing (MIMO-OFDM) provide a promising approach for wireless systems. However, a serious drawback of the OFDM system is the high peak-toaverage power
On-the-residentiall
- 我国目前对噪音污染的治理方法主要有两种：一种是将水泥路 面的改柏油路面第二种是在距离住宅窗户较近的道路两侧安装隔音 屏障。但效果均不理想。路面改变只可降低汽车行驶摩擦声的3～5 分贝左右。至于安装隔音屏障．由于声波的衍射特性，声音的传播可 以跨越隔音屏障，在中频，高频声波传播中，遇到难以穿透的障碍物 时，背面就有一个声波微弱的影区。所以此举只对相近楼层有所缓 解，对更高楼层的住户而言，效果并不明显-Our current treatment methods for noi
20ghz-lna
- A 20-GHz low noise amplifier (LNA) is designed in 0.13 CMOS technology. The proposed amplifier employs twocascade stages to achieve a peak power-gain of 25 dB and a noisefigure of 4.8 dB at 20.4 GHz. The power consumption of the LNA circuit is 12.2
gardnertimingdetector
- This paper presents the simulation performance of the all-digital symbol timing recovery using the Gardner Timing Error Detector over π/4-DQPSK modulation. The open loop statistics, the S-curve and the normalized timing error variance, were investiga
[5]-Sensitive-White-Space-Detection-with-Spectral
- This paper proposes a novel, highly effective spectrum sensing algorithm for cognitive radio and white space applications. The proposed spectral covariance sensing (SCS) algorithm exploits the different statistical correlations of the received
