BASIC CONCEPTS IN WIRELESS
COMMUNICATIONS
1.1 OVERVIEW
In this chapter, we review the important and basic concepts in wireless communications.
In Section 1.2, we first review different types of wireless channel
models, namely, time dispersion, multipath dispersion, and spatial dispersion
in microscopic fading. Concepts of frequency-selective fading, frequency
flat fading, fast fading, slow fading, coherence bandwidth, coherence time, and
coherence distance will be introduced. In Section 1.3, we establish the equivalence
of discrete-time and continuous-time models in wireless comm ... read full excerpt from Channel Adaptive Technologies and Cross Layer Designs for Wireless Systems with Multiple Antennas: Theory and Applications ebook
