Wireless Channel
Explore how wireless channels transmit signals through multiple paths causing inter-symbol interference, and understand why equalization is essential. This lesson models wireless channels as linear systems affecting signal reception and sets the foundation for using OFDM to manage interference effectively.

For this course, we’ll discuss a simple model for a wireless channel and ignore the intricate details like fading, delay spread, Doppler spread, coherence bandwidth, and coherence time.
Multiple paths
In guided media like optical fiber or a coaxial cable, the transmitted signal does not diverge in all three dimensions. On the other hand, a wireless channel is an unguided medium in which a sent signal traces several ...
