Chapter 5. First-Order Channel Statistics

The received power in fading wireless channels fluctuates between maxima and minima as a function of space, time, and frequency. A wireless engineer must accept the fact that for certain regions in space, time, or frequency, the receiver may have to operate with received signal strength below an acceptable signal-to-noise or signal-to-interference ratio. To quantify the effects of a fading channel on receiver performance, we must first quantify the distribution of received power or voltage envelope that a receiver experiences in a randomly selective channel.

This chapter develops the principles of first-order analysis for stochastic frequency-selective and spatially selective radio channels. The most important ...
