Is when a broadcast radio signal reaches the receiver multiple times because it is reflected off of objects and the reflected signal is delayed. This creates ghosting (double images) in analog broadcasts, but it can confuse digital receivers because it does not which one is the primary data stream.

Multipath happens when an incoming signal is bounced off of buildings, trees, cars, and other solid objects. This was where ghost images came from when watching regular analog TV. Instead of getting one signal from the direct source, you would be getting multiple signals that took more time bouncing around before it reached you.

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.

Short for multipath reflection (MPR), it is the phenomenon that arises when RF signals reach an antenna by two or more paths. MPR can be caused by atmospheric phenomena or reflection by objects such as hills or buildings in the signal's path. Ghost images seen on TV are an example of the effects of MPR.

Copies of a broadcast signal arriving at the antenna delayed in time after bouncing off of other objects such as distant hills, the received result being ghosting on the screen.

In addition to direct path from transmitter to receiver there exist several indirect paths. The interference caused due to these indirect paths is called multipath.

Reception of one or more reflected signals along with a direct broadcast signal, producing distortion in stereo FM and ghost images in televisions

refers to a reflected signal that combines with a true signal resulting in a weaker position determination

When a radio or television signal arrives at a receiver from two or more different paths (at least one of which is a reflection) the signals interfere with each other causing distortion in FM audio and ghosting in television pictures. See: Diversity Reception.

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 copies of a single RF signal arriving at a radio receiver's antenna simultaneously. Signals that are in phase will add to one another, and signals that are out of phase will cancel.

A phenomenon in which signals arrive at a receiver by at least two different paths, one of which may be reflected

Radio signals that are reflected metel, concrete, and other materials resulting in multiple duplicate signals being received at the access point or client at different points in time.

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.

When the RF signal arrives at the receiving antenna after bouncing through several paths. Significantly degrades the received signal power.

A condition where one or more echoes or reflections of a TV signal interfere with or cancel out the original TV signal.

The phenomenon of receiving the satellite signal multiple times due to time delays associated with reflection off of surroundings, such as buildings, terrain, etc.; responsible for the "ghosts" on your TV when using rabbit ears; can cause error in GPS position calculations.

The signal variation caused when radio signals take multiple paths from transmitter to receiver.

Interference similar to "ghosts" on a television screen which occurs when GPS signals arrive at an antenna having traversed different paths. Multipath may arise from reflections off structures near the antenna and occurs to some extent everywhere. The signal which traverses a longer path will yield a larger pseudo range estimate and increase the error.

The multiple paths a radio wave may follow between transmitter and receiver. In cellular communications, refers to a radio signal reaching the receiving antenna by two or more paths. See Also: Multipath Fading

Propagation that arrives at a receiver having travelled over different paths, and consequently arrives at slightly different times, with potentially slightly different phases.

An error caused when a satellite signal reaches the GPS receiver antenna by more than one path. Usually caused by one or more paths being bounced or reflected. The TV equivalent of multipath is "ghosting."

Refers to a radio signal that winds up taking two or more paths because the signal is reflected off buildings or other obstructions. Although multipath is a problem with all kinds of radio transmission, ghosts on a TV channel are an example of multipath that you can see with your own eyes.

Multipath happens when an incoming signal is bounced off of buildings, trees, cars, and other solid objects. This was where ghost images came from when watching regular analog TV. Instead of getting one signal from the direct source, you would be getting multiple signals that took more time bouncing around before it reached you.

In wireless telecommunications, multipath is the propagation phenomenon that results in radio signals' reaching the receiving antenna by two or more paths. Causes of multipath include atmospheric ducting, ionospheric reflection and refraction, and reflection from terrestrial objects, such as mountains and buildings.
