Coherence bandwidth is a statistical measure of the range of frequencies over which a communication channel can be considered 'flat' or frequency-nonselective, meaning the channel's gain and phase response are approximately constant. It is crucial for understanding how multipath effects impact signal transmission and is inversely related to the delay spread of the channel.

A statistical measure is a value that represents a characteristic of a dataset, providing insights into its distribution, central tendency, or variability. These measures are essential for summarizing data, making comparisons, and drawing conclusions in research and data analysis.

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 effects occur when signals reach a receiving antenna by multiple paths, causing interference and signal distortion. This phenomenon is significant in wireless communication, affecting signal quality and reliability, especially in urban environments with numerous reflecting surfaces.

multipath effects

Signal transmission refers to the process by which information is conveyed from one place to another, typically using electromagnetic waves or electrical impulses. It is fundamental to communication systems, enabling data exchange over distances in various forms such as analog, digital, and optical signals.
