  • Multichannel TransmissionTransmit Diversity and SpaceTime Coding

    In this chapter, we first introduce the notion of transmit diversity, which shifts the complexity associated with the implementation of a diversity receiver to the transmitter with the hope of accomplishing the same purpose, specifically, providing diversity gain, with as little compromise as possible in average SNR performance. In the simplest of terms, we transmit the same signal information (over a multitude of symbol intervals and not necessarily in the same sequence) simultaneously from a multitude of antennas and appropriately combine the faded versions of these transmissions received in the multitude of symbol intervals in such a way as to provide a diversity gain.

  • Future Research Directions

  • Capacity of Fading Channels

    Goldsmith and Varaiya derived the capacity of a single-user flat-fading channel with channel measurement information at the transmitter and receiver for various adaptive transmission policies. In this chapter, we first apply the general theory that they developed and present closed-form expressions for the capacity of Rayleigh fading channels under different adaptive transmission schemes with and without diversity combining. In particular, we consider three adaptation policies: optimum simultaneous power and rate adaptation, constant power with optimum rate adaptation, and channel inversion with fixed rate. We then investigate the impact of maximal-ratio diversity (MRC) on the Shannon capacity in conjunction with each of these adaptive transmission schemes.

    A variety of problems in machine learning and digital communication deal with complex but structured natural or artificial systems. In this book, Brendan Frey uses graphical models as an overarching framework to describe and solve problems of pattern classification, unsupervised learning, data compression, and channel coding. Using probabilistic structures such as Bayesian belief networks and Markov random fields, he is able to describe the relationships between random variables in these systems and to apply graph-based inference techniques to develop new algorithms. Among the algorithms described are the wake-sleep algorithm for unsupervised learning, the iterative turbodecoding algorithm (currently the best error-correcting decoding algorithm), the bits- back coding method, the Markov chain Monte Carlo technique, and variational inference.

  • Quantization Noise Spectra

    Uniform qunntizers play a fundamental role in digital communication systems and have been the subject of extensive study for many decades, The inherent nonlinearity of quantizers makes their analysis hoth difficult and Interesting, It usually has been accomplished either by assuming the quantizer noise to be a signal-independent, uniform white random process or by replacing the quantizer by a deterministic linear device, or by combining the two assumptions. Such linearizing approximations simplify the analysis and permit the use of linear systems techniques, but few results exist quantifying how good such approximations are for specific systems, These complications are magnified when the quantizer is inside a feedback loop, as for Sigma-Delta modulators. Exact descriptions of the moments and spectra of quantizer noise have been developed recently for the special case of single-loop, multistage and multiloop Signul-Delta modulators. These results demonstrate. that the white noise and linearization assumptions can be quite poor approximations in some systems and quite good in others. It turns out that many of the techniques used in the analysis were first applied to the analysis of quantizers by Clavier, Panter, and Grieg (1947) in pioneering (but often overlooked) work that preceded Bennett's (1948) classic study of quantization noise spectra. We take advantage of the benefit of hindsight to develop several results describing the behavior of quantization noise in a unified and simplified manner. Exact formulas for quantizer noise spectra are developed and applied to a variety of systems and inputs, including scalar quantization (PCM), dithered PCM, Sigma-Delta modulation, dithered Sigma-Delta modulation, two-stage Sigma-Delta modulation, and second-order Sigma-Delta modulation.

  • The Effects of Time Delay Spread on Portable Radio Communications Channels with Digital Modulation

    Frequency-selective fading caused by multipath time delay spread degrades digital communication channels by causing inter-symbol interference, thus resulting in an irreducible BER and imposing a upper limit on the data symbol rate. In this paper, a frequency-selective, slowly fading channel is studied by computer simulation. The unfiltered BPSK, QPSK, OQPSK, and MSK modulations are considered first to illustrate the physical insights and the error mechanisms. Two classes of modulation with spectral-shaping filtering are studied next to assess the tradeoff between spectral occupancy and the performance under the influence of time delay spread. The simulation is very flexible so that different channel parameters can be studied and optimized either individually or collectively. The irreducible BER averaged over fading samples with a given delay profile is used to compare different modulation/detection methods, while the cumulative distribution of short-term BER is employed to show allowable data symbol rates for given values of delay spread. It is found that both GMSK and QPSK with a raised-cosine Nyquist pulse are suitable for a TDM/TDMA digital portable communications channel.

  • Outage Performance of Multiuser Communication Systems

    In this chapter, we present first a generic closed-form expression for the evaluation of the outage probability in interference-limited systems when the interferers are assumed to be subject to independent, identically distributed (i.i.d) fading. We then study multiuser systems that are not necessarily interference-limited and for which outage occurs when either the carrier-to- interference ratio (CIR) or the carrier-to-noise ratio (CNR) is less than its respective predetermined threshold value. Next, we quantify the reduction in the outage probability obtained when using low-complexity diversity combining schemes. We finally look into the combined effect of fading and cochannel interference on the outage rate and the average outage duration (AOD) of multiuser communication systems. It should be noted that the scope of our analysis in this chapter is limited to the effect of multipath fading and does not take into account the impact of lognormal shadowing.
