It is shown that time-division adaptive retransmission used with appropriate antenna configurations can also mitigate these effects.

  • Interconnections and Settlements

    For years, the world saw the Internet as a creature of theU.S. Department of Defense. Now some claim that the Internet is aself-governing organism controlled by no one and needing nooversight. Although the National Science Foundation and othergovernment agencies continue to support and oversee criticaladministrative and coordinating functions, the Internet is remarkablydecentralized and uninstitutionalized. As it grows in scope,bandwidth, and functionality, the Internet will require greatercoordination, but it is not yet clear what kind of coordinatingmechanisms will evolve.The essays in this volume clarify these issues and suggest possiblemodels for governing the Internet. The topics addressed range fromsettlements and statistics collection to the sprawling problem ofdomain names, which affects the commercial interests of millions ofcompanies around the world. One recurrent theme is the inseparabilityof technical and policy issues in any discussion involving theInternet.Contributors:Guy Almes, Ashley Andeen, Joseph P. Bailey, Steven M.

  • A LowNoise FastLock PhaseLocked Loop with Adaptive Bandwidth Control

    This paper presents a salient analog phase-locked loop (PLL) that adaptively controls the loop bandwidth according to the locking status and the phase error amount. When the phase error is large, such as in the locking mode, the PLL increases the loop bandwidth and achieves fast locking. On the other hand, when the phase error is small, this PLL decreases the loop bandwidth and minimizes output jitters. Based on an analog recursive bandwidth control algorithm, the PLL achieves the phase and frequency lock in less than 30 clock cycles without pre-training, and maintains the cycle-to-cycle jitter within 20 ps (peak-to-peak) in the tracking mode. A feed forward-type duty-cycle corrector is designed to keep the 50% duty cycle ratio over all operating frequency range.

  • TESLA-based Broadcast Authentication

    This chapter explores ways to use fast symmetric cryptography to protect vehicular communications, but without direct involvement of RSUs. It focuses on the timed efficient stream loss-tolerant authentication (TESLA) authentication protocol, which is commonly used in securing broadcast and multicast communication. In addition, since only a short message authentication code (MAC) tag is attached to each message, the extra message length and the bandwidth overhead due to the security mechanism can be significantly reduced. The chapter presents the design of a TESLA-based broadcast authentication scheme for vehicular communication, termed TSVC. It begins by providing a brief introduction to the techniques used here, which serve as the basis for the proposed scheme, and then presents the scheme. Finally, the chapter analyzes security through rigorous analysis and conducts performance evaluations through extensive simulation.

  • Dynamics and Control

    This chapter examines the fundamental aspects of modular multilevel converter (MMC) dynamics and control. It starts with a description of the converter topology for the purpose of dynamic modeling. An averaged dynamic model is then derived which constitutes the basis for the control¿¿?system design. The control loop for the output current has the highest bandwidth of all nested control loops; its design is analyzed here. Arm¿¿?balancing control stage includes control of the circulating current and of the sum capacitor voltages. General theory for three¿¿?phase systems and space vectors is considered, before revisiting output¿¿?current control but using space vectors in a synchronously rotating reference frame. The first block in the chain is the higher¿¿?level control, which includes the phase¿¿?locked loop (PLL) that is used for grid synchronization, active and reactive¿¿?power control, DC¿¿?bus¿¿?voltage control, and the principle of power¿¿?synchronization control.

  • Nine Digital Filters for Decimation and Interpolation

    Filtering is necessary in decimation (decreasing the sampling rate of) or interpolation (increasing the sampling rate of) a digital signal. If the rate change is substantial, the process is mote efficient when the decimation or interpolation occurs in stages rather than in one step. Half-band filters are particularly efficient for effecting octave changes in sampling rate and nine digital filters are presented, eight of them half-band filters, to be used as components of multistage interpolators and decimators. Also presented is a procedure for combining the filters to produce multistage designs that meet a very wide range of accuracy requirements (stopband attenuation to 77 dB, passband ripple as low as 0.00014). The nine filters admit changes between sampling rates above 4 _W_, where _W_ is the nominal bandwidth of the signal. Established design techniques may be used to obtain efficient filters for conversion between 4_W_ Hz sampling and 2_W_ Hz, the ?>baseband sampling rate.?> With these multistage filters, the possible interpolation and decimation ratios are all integer multiples of powers of two. To overcome this restriction we present a simple resampling technique that extends the range of designs to conversions between any two rates. The interpolation or decimation ratio need not be an integer or even rational. In fact, it can vary slightly as in a practical situation where the input signal and output signal are under the control of autonomous clocks. We demonstrate the approach by means of several design examples and compare its results with those obtained from the optimization scheme of Crochiere and Rabiner.

  • Fundamental Limitations in Passive Time Delay EstimationPart I: NarrowBand Systems

    Time delay estimation of a noise-like random signal observed at two or more spatially separated receivers is a problem of considerable practical interest in passive radar/sonar applications. A new method is presented to analyze the mean-square error performance of delay estimation schemes based on a modified (improved) version of the Ziv-Zakai lower bound (ZZLB). This technique is shown to yield the tightest results on the attainable system performance for a wide range of signal-to-noise ratio (SNR) conditions. For delay estimation using narrow-band (ambiguity-prone) signals, the fundamental result of this study is illustrated in Fig. 3. The entire domain of SNR is divided into several disjoint segments indicating several distinct modes of operation. If the available SNR does not exceed SNR1, signal observations from the receiver outputs are completely dominated by noise thus essentially useless for the delay estimation. As a resuit, the attainable mean-square error -2 is bounded only by the a priori parameter domain. If SNR1 > SNR > SNR2, the modified ZZLB coincides. with the Barankin bound. In this regime differential delay observations are subject to ambiguities. If SNR < SNR3 the modified ZZLB coincides with the Cramer-Rao lower bound indicating that the ambiguity in the differential delay estimation can essentially be resolved. The transition from the ambiguity-dominated mode of operation to the ambiguity-free mode of operation starts at SNR2 and ends at SNR3. This is the threshold phenomenon in time delay estimation. The various deflection points SNRi and the various segments of the bound (Fig. 3) are given as functions of such important system parameters as time-bandwidth product (WT), signal bandwidth to center frequency ratio (W/0) and the number of half wavelengths of the signal center frequency contained in the spacing between receivers. With this information the composite bound illustrated in Fig. 3 provides the most complete characterization of the attainable system performance under any prespecified SNR conditions.
