Abstract

In this chapter, we summarize the main facts, which characterize a wireless single input single output channel. Such channels can be partitioned into different segments. The inner part is the wave propagation channel, which is characterized by the free space between the output of the transmit antenna and the input to the receive antenna. The next level includes the characteristics of the transmit and the receives antenna, such as radiation pattern and antenna gains. Finally, the equivalent baseband system incorporates modulation, demodulation, and filtering, as described in Sect. 5.1. In the following, we characterize the main transmission effects of wireless and mobile channels with adequate models. There are several physical details for refinements, which are beyond our scope here, such as specific indoor and outdoor scenarios as well as details of electromagnetic field theory.
