Multipath propagation — This article is about the electromagnetic propagation phenomenon. For the computing storage term, see Multipath I/O. For the routing term, see Multipath Routing. In wireless telecommunications, multipath is the propagation phenomenon that results … Wikipedia
Spread spectrum — Passband modulation v · d · e Analog modulation AM · … Wikipedia
Delay spread — In telecommunications, the delay spread is a measure of the multipath richness of a communications channel. In general, it can be interpreted as the difference between the time of arrival of the earliest significant multipath component (typically … Wikipedia
Coherence bandwidth — is a statistical measurement of the range of frequencies over which the channel can be considered flat , or in other words the approximate maximum bandwidth or frequency interval over which two frequencies of a signal are likely to experience… … Wikipedia
Orthogonal frequency-division multiplexing — Passband modulation v · d · e Analog modulation AM · … Wikipedia
Code division multiple access — This article is about a channel access method. For the mobile phone technology referred to as CDMA, see IS 95 and CDMA2000. Multiplex techniques Circuit mode (constant bandwidth) TDM · FDM … Wikipedia
Digital Radio Mondiale — (abbreviated DRM; mondiale being Italian and French for worldwide ) is a set of digital audio broadcasting technologies designed to work over the bands currently used for AM broadcasting, particularly shortwave. DRM can fit more channels than AM … Wikipedia
Fading — This article is about signal loss in telecommunications. For the poetry book, see Fading (book). For other uses, see Fade (disambiguation). Frequency selective time varying fading causes a cloudy pattern to appear on a spectrogram. Time is shown… … Wikipedia
Intersymbol interference — In telecommunication, intersymbol interference (ISI) is a form of distortion of a signal in which one symbol interferes with subsequent symbols. This is an unwanted phenomenon as the previous symbols have similar effect as noise, thus making the… … Wikipedia
Fuzzy locating system — Fuzzy locating is a rough but reliable method based on appropriate measuring technology for estimating a location of an object. The concept of precise or ‘’crisp locating’’ is replaced with respect to the operational requirements and the economic … Wikipedia
Carrier interferometry — (CI) is a type of spread spectrum multiple access typically employed with Orthogonal frequency division multiplexing (OFDM). CI spreading codes are commonly used to spread data symbols across multiple OFDM subcarriers for diversity benefits and… … Wikipedia
