Envelope fading refers to the variation in amplitude of a signal as it passes through a communication channel, often caused by multipath propagation where the signal takes multiple paths to the receiver. This phenomenon can lead to signal degradation, affecting the reliability and quality of wireless communication systems.

A communication channel is the medium through which information is transmitted from a sender to a receiver, and it plays a critical role in determining the effectiveness and clarity of the communication process. Understanding the characteristics and limitations of different channels is essential for selecting the most appropriate one for a given context or message type.

Multipath propagation occurs when transmitted signals reach a receiving antenna by multiple paths due to reflection, diffraction, and scattering. This phenomenon can cause signal fading, interference, or enhancement, impacting the reliability and quality of wireless communication systems.

Signal degradation refers to the loss of quality or strength of a signal as it travels through a medium, leading to errors or loss of information. It is a critical consideration in communication systems, where maintaining signal integrity is essential for accurate data transmission.
