Doppler effect

View this topic in
The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. (

  • OFDM Receiver with Clustered Channel Adaptation

    This chapter presents an orthogonal frequency‐division multiplexing (OFDM) receiver leveraging the measurements from both the current and past blocks. This allows the system to reduce the number of pilots while maintaining robust operation over fast‐varying channels. The chapter illustrates channel dynamics, notably different variations across multipath clusters. It presents a cluster‐based channel variation model to parameterize the channel variation from block to block. The chapter describes the design of an adaptive OFDM receiver, developing key receiver modules incorporating channel adaptation. It contains performance results of the block‐to‐block adaptive receiver using data sets collected in two field experiments, MACE10 and SPACE08.

  • Applications to Mobile Communications and Radar/Sonar

    In Chapter 7, applications in mobile communications and radar/sonar systems are presented. A model for the wireless channel is developed. It is shown how, in the case of relative motion between transmitter and receiver or between radar and target, the almost-cyclostationary transmitted signal is modified into a received signal with a different kind of nonstationarity. Conditions under which the generalized almost-cyclostationary or spectrally correlated model are appropriate for the received signal are derived.

  • Bibliographic Notes

    In Chapter 8, citations are classified into categories and listed in chronological order.

  • Receiver Overview and Preprocessing

    This chapter provides an overview on the OFDM receiver structure for three types of channel settings: (i) the single‐input single‐output (SISO) channel, (ii) the single‐input multi‐output (SIMO) channel, and (iii) the multi‐input multi‐output (MIMO) channel. It focuses on receiver preprocessing which converts the analogous time‐domain waveform to the frequency‐domain discrete samples. After the receiver preprocessing, the input-output relationship between frequency samples and transmitted data symbols in the above three types of channel settings are presented. A general overview on OFDM receivers is provided based on two data decoding philosophies. The chapter analyzes he system model for CP‐OFDM transmissions, and highlights the subtle difference between ZP‐OFDM and CP‐OFDM receiver designs. Finally, it provides numerical results on the OFDM receiver theoretical performance bound.

  • Introduction

    This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book provides the fundamentals of both empirical measurement¿¿¿based and theoretical¿¿¿scattering¿¿¿based channel modeling. The statistical characteristics of channels can significantly influence the design of wireless communication systems. The channel characteristic of interest when the single¿¿¿input, single¿¿¿output (SISO) system was considered was therefore the fading distributions at particular frequencies. In the spatial channel model, clustering of multiple paths is a necessary step for generating the small¿¿¿scale parameters of the channel, such as the cluster delay spread, cluster angular spread, and the time¿¿¿variant behavior of the clusters. Future generations of wireless communication systems will employ new techniques that rely on channel modeling for more complex network constellations. Some models focus on the specific behavior of the channels, such as their reciprocity behavior with respect to time and frequency, their polarization characteristics, interference, and the line¿¿¿of¿¿¿sight (LoS) and NLoS probabilities.
