In radio communication, 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 water bodies and terrestrial objects such as mountains and buildings.
Despite the great potential complexity and diversity of biological networks, all first-order network behavior generalizes to one of four possible input-output motifs: hyperbolic or Michaelis–Menten, ultra-sensitive, bistable, and bistable irreversible (a bistability where negative and therefore biologically impossible input is needed to return from a state of high output).
Multipath routing is a routing technique simultaneously using multiple alternative paths through a network. This can yield a variety of benefits such as fault tolerance , increased bandwidth , and improved security .
The accuracy of the TOA based methods often suffers from massive multipath conditions in indoor localization, which is caused by the reflection and diffraction of the RF signal from objects (e.g., interior wall, doors or furniture) in the environment.
A rake receiver utilizes multiple correlators to separately detect the M strongest multipath components. Each correlator output may be quantized using several bits. Demodulation and bit decisions are then based on the weighted outputs of the M correlators, which provide a better estimate of the transmitted signal than is provided by a single c
In radio, multiple-input and multiple-output (MIMO) (/ ˈ m aɪ m oʊ, ˈ m iː m oʊ /) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation.
The multipath effect occurs when a signal is received not only through a Line of Sight (LOS) path, but also through one or several NLOS paths. The multipath, if not addressed or compensated, can significantly reduce the performance of the communication and navigation receivers. Various multipath mitigation methods can be used to estimate and ...
Multipath TCP (MPTCP) is an ongoing effort of the Internet Engineering Task Force's (IETF) Multipath TCP working group, that aims at allowing a Transmission Control Protocol (TCP) connection to use multiple paths to maximize throughput and increase redundancy.
