Involving or pertaining to more than one path (route), as between nodes on a network or components in a computer
A wireless propagation phenomenon that results in a signal reaching the receiving antenna by two or more paths
– Interference similar to ghosts on a television screen which occurs when GPS signals arrive at an antenna after traversing different paths The signal traversing the longer path will yield a larger pseudo range estimate and increase the error Multipath paths may arise from reflections from structures near the antenna
Interference caused by reflected GPS signals arriving at the receiver, typically as a result of nearby structures or other reflective surfaces Signals traveling longer paths produce higher (erroneous) pseudorange estimates and consequently ,positioning errors
Interference similar to "ghosts" on a television screen which occurs when GPS signals arrive at an antenna having traversed different paths The signal traversing the longer path will yield a larger pseudo range estimate and increase the error Multiple paths may arise from reflections from structures near the antenna
The process by which a transmitted signal arrives at the receiver by at least two different paths These paths are usually the main direct path, and at least one reflected path The signals combine either constructively or destructively depending upon phase, and the resultant signal may be either stronger or weaker than the value computed for free space
Interference similar to ‘ghosting’ on a television screen which occurs when GPS signals arrive at an antenna having traversed different paths (e g after getting reflected from buildings) The different paths yield different pseudo range estimates and introduce errors into computed GPS positions
The propagation phenomenon that results in radio signals reaching the receiving antenna by two or more paths
When a transmitted signal arrives at a receiver by two or more paths of different transmission times The out-of-phase reception of several copies of the signal can cause error in signal reception
Multipath is the reception of a signal both along a direct path and along one or more reflected paths Multipath signals result in an incorrect pseudorange measurement
The reception of a radio signal from more than one path One may be direct and the rest reflected, or all may be reflected The resulting signal results in an incorrect measurement
The presence of multiple signals arriving at the receiver antenna simultaneously Signals that are in phase will add to one another Signals that are out of phase will cancel one another
refers to a common phenomenon in RF where the signal arrives multiple times at the receiver at slightly different times If you've used a TV with an old-style rabbit-ear antenna, you've sometimes seen ghosting, where the video seems to have echos of itself extending to the right This is due to multipath Usually the strongest path is nearly direct from the transmitter to the receiver However, the signal can reflect off of other objects (large buildings are particularly good at this) and that signal arrives somewhat later, since it follows a somewhat longer path For most kinds of RF multipath is a form of interference and degrades the signal CDMA is unique among cellular transmission standards in that it actually uses multipath to its advantage by using fingers in the rake receiver As a result, CDMA performance is actually improved by multipath
  The propagation phenomenon that results in radio signals' reaching the receiving antenna by two or more paths (188)  Note 1: Causes of multipath include atmospheric ducting, ionospheric reflection and refraction, and reflection from terrestrial objects, such as mountains and buildings   Note 2:   The effects of multipath include constructive and destructive interference, and phase shifting of the signal   Note 3: In facsimile and television transmission, multipath causes jitter and ghosting
RF signals arriving at a location via different transmission paths, usually referring to a combination of direct and reflected signals The direct and reflected signals are often opposite in phase, which can result in a significant signal loss due to mutual cancellation in some circumstances Multipath is most troublesome indoors and in areas where many metallic surfaces are present
The echoes created as a radio signal bounces off of physical objects
Multipath is the composition of a primary signal plus duplicate or echoed images caused by reflections of signals off objects between the transmitter and receiver The receiver "hears" the primary signal sent directly from the transmission facility, but it also sees secondary signals that are bounced off nearby objects These bounced signals will arrive at the receiver later than the incident signal Because of this misalignment, the "out-of-phase" signals will cause intersymbol interference or distortion of the received signal Although most of the multipath is caused by bounces of tall objects, multipath can also occur from bounces on low objects such as lakes and pavements
