Physically Degraded Gaussian Broadcast Channel Feedback
2015/8/12
Bounds on the output entropy of the additive white Gaussian noise (AWGN) channel with feedback are used to prove that the capacity of the degraded additive white Gaussian noise (DAWGN) broadcast chann...
An Outer Bound to the Capacity Region of the Broadcast Channel
Outer Bound Capacity Region Broadcast Channel
2015/8/12
An outer bound to the capacity region of the two-receiver discrete memoryless broadcast channel is given. The outer bound is tight for all cases where the capacity region is known. When specialized to...

一种应用于数字电视中的CMOS宽带高线性LNA设计
低噪声放大器 宽带 高线性 噪声抵消
2015/10/29
基于TSMC 0.13 μm CMOS工艺设计了一款应用于数字电视中的CMOS宽带高线性低噪声放大器。该电路采用传统宽带低噪声放大器的改进结构。为了提高LNA的线性度，采用伏尔特拉级数分析了电路的非线性分量，并修正了传统的噪声抵消电路用于抵消整个电路的非线性分量。基于TSMC 0.13 μm CMOS工艺对其进行了设计，仿真结果表明：此LNA在50～860 MHz频带内，增益为12.7～13.3 ...
近年来，全球家用电视机正在更新换代，老式的电视阴极射线管（CRT）正在被新型的平面液晶（LCD）、等离子（Plasma）和发光二极管（LED）显示器所替代。堆积如山的废弃阴极射线管，含有铅（Lead）或磷（Phosphor）等危险化合物成分，必须得到妥善的回收处理。否则，日积月累，必将对人体健康和生态环境造成不可估量的严重伤害。但阴极射线管的回收处理与循环再利用，因其回收材料的价值原因，一直是废弃...
