This chapter studies the effect of fading channels on digital wireless transmission. After reviewing the basics of digital bandpass modulation, we investigate the effect of channel phase and channel amplitude on the detection performance of linear modulation schemes. Finally, we present the statistical fading channel models for various fading scenarios and apply them to the performance analysis of digital wireless transmission, in terms of outage probability and average error rate.
