A Workshop was held in Tucson in September 2000 to define a layout for the optics and dewar. Section 3 lists the design goals for the Workshop, and the configuration that emerged is detailed in this document. This includes the overall arrangement, and the details of the optics of the individual Bands. These bands are those defined by Wootten et al. [1] and endorsed with minor adjustment for Ban...

An essential parameter in determining the system power budget in an optical transmission system is optical receiver sensitivity, defined as the minimum average optical power for a given bit-error rate (BER). When designing a good optical receiver, it is critical to understand the different parameters that will impair overall receiver sensitivity. This article provides an indepth analysis of com...

In Internet data transmission, the throughput of 45 Mbps is achieved. Now the goal is to increase the data rate further to 100 Mbps and beyond. We designed a Frequency Division Multiple Access system for that and realized it using Q-Dot technology. The principal reason for coherent demodulation in LAN is the size of PLL in QDot circuit. It also allows higher capacity than 1⁄2 achieved so far. 1...

We introduce a receiver-oriented approach to congestion control, demonstrated by an experimental protocol, TCP-Real. The protocol allows for a measurement-based transmission strategy, which complements the "blind" increase/decrease window adjustments. Owing to its design, the protocol displays an inherent property to produce comprehensive dynamics in heterogeneous environments with wired or wir...

Preface Wireless standards are subject to rapid development and frequent changes, making old hardware obsolete at a high rate. On the other hand, the constantly increasing computational power of general purpose computers allows developers to move functionality away from hardware and specialized processors, to high-level software running on arbitrary general purpose processors. This leads to the...

The preceding chapter considered the design of receivers for MIMO systems operating as single-user systems. Increasingly however, as noted in Chapters 2 and 4, wireless communication networks operate as shared-access systems in which multiple transmitters share the same radio resources. This is due largely to the ability of shared access systems to support flexible admission protocols, to take ...

The Galileo system introduces an extremely wideband civil E5 signal for high precision navigation. The structure of the receiver for the E5 signal is complicated due to the signal complexity and the large bandwidth. It is possible to process the whole E5 signal or process separately E5a and E5b parts combining obtained results afterwards (we call here such method as piece-wise processing). The ...

Receiver operating characteristic (ROC) curves are useful statistical tools for medical diagnostic testing. It has been proved its capability to assess diagnostic marker’s ability to distinguish between healthy and diseased subjects and to compare different diagnostic markers. In this paper we introduce non parametric ROC summary statistics to assess a ROC curve across the entire range of FPFs ...
