This book was released on 1973 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: Receivers are designed for a pulse amplitude modulation digital communication system with additive white Gaussian noise and intersymbol interference. Considered along with the transversal filter receiver are the bit detector and block detector. The bit detector minimizes the probability of error in the decision on each data digit; the block detector minimizes the probability of error in making a joint decision on the entire sequence of data digits. The three receivers are compared in noniterative form on the fixed, known channel. The sampled autocorrelation function of the basic PAM pulse waveform determines the signal-space geometry and, along with the noise spectral density, the error probability of the three receivers. The output of a bank of matched filters, one matched to each translate of the basic PAM waveform, constitutes a sufficient statistic for the realization of all three receivers.

Book Synopsis Time Varying Channels by : Nathan D. Ricklin
Download or read book Time Varying Channels written by Nathan D. Ricklin and published by . This book was released on 2010 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is concerned with digital communications systems operating over channels that vary in time due to mobility of the transmitter or receiver. Velocity of the transmitter or receiver causes a Doppler shift or smearing in frequency which hinders parameter estimation and degrades data detection performance. To aid in our goal of improved estimation and detection performance, we discuss several characterization methods, both probabilistic and deterministic, that can accurately model the time-varying channel and that enable efficient parameter estimation and data detection. The first topic we address is that of carrier frequency offset estimation in the presence of a time-varying frequency-selective channel. The scheme is data-aided, meaning that a block of pilot data known to the receiver is first transmitted through the channel. Joint estimators of both the CFO and the time-varying frequency-selective channel are developed using both probabilistic and deterministic channel models. The probabilistic CFO estimator is shown to achieve the Cramer-Rao Lower Bound, and the deterministic estimator can perform well, but depends heavily on the choice of channel parameterization in the deterministic model. The second topic we focus on is concerned with blind data detection over time-varying channels. The problem we consider is recovery of a short block of time-domain data symbols transmitted over a channel with time-varying multiplicative distortion. The receiver does not know the data, the channel, or any statistics that could parameterize a probabilistic description of the channel. We design data detection algorithms based on a deterministic parameterization of the channel that can be implemented efficiently with the sphere decoding algorithm. Additionally we provide techniques for a priori selection of the channel parameterization that result in near-optimal performance over a wide range of channel conditions. In our final topic we consider blind detection over a frequency-selective time-varying channel. A short block of symbols is transmitted in the frequency domain, as either an OFDMA frequency allocation or as a subset of a larger OFDM symbol. The multiplicative distortion across the symbols is varying, due to frequency-selectivity. In addition, the transmitted symbols interfere with one another due to the channel time-variation, manifested as intercarrier interference. We introduce a novel method of correlatively coding the symbols across frequency before transmission that reduces the power of the ICI at the receiver. The scheme results in transmitted symbols that are constant in magnitude, which enables the application of efficient detection algorithms also based either probabilistic or deterministic parameterization of the channel. The resulting blind detector is efficient and can outperform an OFDM system which knows the channel perfectly.
Book Synopsis Introduction to Digital Communications by : Joachim Speidel
Download or read book Introduction to Digital Communications written by Joachim Speidel and published by Springer Nature. This book was released on 2021-04-02 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers students, scientists, and engineers an extensive introduction to the theoretical fundamentals of digital communications, covering single-input single-output (SISO), multiple-input multiple-output (MIMO), and time-variant systems. Further, the main content is supplemented by a wealth of representative examples and computer simulations. The book is divided into three parts, the first of which addresses the principles of wire-line and wireless digital transmission over SISO links. Digital modulation, intersymbol interference, and various detection methods are discussed; models for realistic time-variant, wireless channels are introduced; and the equivalent time-variant baseband system model is derived. This book covers two new topics such as blockwise signal transmission and multicarrier modulation with orthogonal frequency-division multiplexing (OFDM) systems. Since not all readers may be familiar with this topic, Part II is devoted to the theory of linear time-variant systems. The generalized convolution is derived, and readers are introduced to impulse response, the delay spread function, and system functions in the frequency domain. In addition, randomly changing systems are discussed. Several new examples and graphs have been added to this book. In turn, Part III deals with MIMO systems. It describes MIMO channel models with and without spatial correlation, including the Kronecker model. Both linear and nonlinear MIMO receivers are investigated. The question of how many bits per channel use can be transmitted is answered, and maximizing channel capacity is addressed. Principles of space–time coding are outlined in order to improve transmission quality and increase data rates. In closing, the book describes multi-user MIMO schemes, which reduce interference when multiple users in the same area transmit their signals in the same time slots and frequency bands.
