Abstract
This chapter covers RF channel models including propagation and antenna. From modem point of view, all the components in RF, e.g., LO, LNA, and PA, are part of channel. However, this chapter covers antenna, propagation media, frequency-selective fading due to surrounding terrains and obstacles, and time-selective fading due to the movement of transmitter and receiver. The measurement of RF channel is covered briefly as well. Channel models used in standards and LEO channel models are included as well.
