    Fundamentals of Time-Varying Communication Channels Gerald Matz and Franz Hlawatsch Vienna University of Technology Introduction Wireless communication systems, i.e., systems transmitting information via electromag-netic (radio) or acoustic (sound) waves, have become ubiquitous. In many of these sys-tems, the transmitter or the receiveris. Chapter in Wireless Communications over Rapidly Time-Varying Channels, F. Hlawatsch and G.

Here, intercarrier interference (ICI) is the major source of impairment that limits the transmission quality. In this paper, we propose novel equalizers to combat ICI and enable reliable communications even at high Doppler frequencies.

2 The wireless channel A good understanding of the wireless channel, its key physical parameters and the modeling issues, lays the foundation for the rest of the book.

This is the goal of this chapter. A defining characteristic of the mobile wireless channel is the variations of the channel strength over time and over frequency. The variations.

CHAPTER 7 OFDM Communications over Time-Varying Channels OFDMSystems System Model Effects of Rapidly Time-Varying Channels MIMO-OFDM ICI Mitigation Techniques Linear Equalization Nonlinear Equalization Transmitter Preprocessing Extension to MIMO-OFDM Under these conditions, the resulting time variation due to Doppler scaling effects, coupled with dispersive scattering due to multipath propagation, can severely limit the receiver performance.

Thus, a wideband channel model needs to be considered at the receiver to improve performance. Wireless Communications Over Rapidly Time-Varying Channels. 2 CHAPTER 1 Fundamentals of Time-Varying Communication Channels Finally, Section discusses the measurement of LTV channels and of their statistics.

Throughout this chapter, we will consider noise-free systems since our focus is on the signal distortions. This chapter presents wideband time-varying channel models and their application towards improving wireless communication performance. It investigates two types of wideband channels: the wideband delay-scale channel that causes multipath and Doppler scaling on the transmitted signal and the wideband dispersive channel that causes nonlinear dispersive changes on the transmitted signal.

Summary: As a result of higher frequencies and increased user mobility, researchers and systems designers are shifting their focus from time-invariant models to channels that vary within a block.

This book explains the latest theoretical advances and practical methods to give an understanding of rapidly time varying channels, together with performance trade-offs and potential performance gains. The emergence of wireless systems that require more and more bandwidth means the task of conquering the wireless channel is becoming more difficult.

This chapter presents an overview of channel modeling history in the context of wireless communications and demonstrates the need for studying the full space–time wireless channel.
