MULTIPATH Meaning and
Definition
-
Multipath is a term used in the field of telecommunications and signal processing, referring to the phenomenon where a transmitted signal reaches the receiver via multiple paths. In multipath propagation, the signal encounters obstacles or reflects off surfaces, leading to the formation of additional paths. These paths can vary in terms of distance, time, and amplitude, causing interference and distortion in the received signal.
When a transmitted signal encounters multipath, it reaches the receiver through different paths, each with a different path length. As a result, the signal components arriving via various paths might experience phase shifts and arrive at the receiver at different times. This leads to constructive or destructive interference, affecting the quality and reliability of the received signal. The interference results in fading, signal attenuation, and even complete loss of signal strength.
Multipath propagation is commonly observed in urban environments, where signals reflect off the buildings, trees, and other obstacles. It also occurs in radio and wireless communication systems, such as Wi-Fi and cellular networks. To mitigate the negative effects of multipath, various techniques are employed, including equalization, diversity reception, and adaptive filtering. These methods aim to compensate for the interference caused by multipath propagation, allowing for better signal quality and reliable communication.
Common Misspellings for MULTIPATH
Etymology of MULTIPATH
The word "multipath" originates from the combination of two terms: "multi-" and "path".
The prefix "multi-" is derived from the Latin word "multus", meaning "many" or "multiple". It is often used as a prefix to indicate "many" or "multiple" instances of something.
The term "path" is derived from the Old English word "paþ" and has roots in the Proto-Germanic language. It refers to a way or a course of action.
When these two terms are combined, "multipath" is formed, signifying "many paths" or "multiple paths". In various fields such as telecommunications or signal propagation, multipath refers to the phenomenon where signals or waves travel through multiple paths, resulting in interference or distortion.
