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
Coherence (physics) — In physics, coherence is a property of waves that enables stationary (i.e. temporally and spatially constant) interference. More generally, coherence describes all properties of the correlation between physical quantities of a wave. When… … Wikipedia
Coherence (signal processing) — Contents 1 Background 2 Definition and Formulation 3 Example 4 Extension to non stationary signals 5 … Wikipedia
Coherence time — For an electromagnetic wave, the coherence time is the time over which a propagating wave (especially a laser or maser beam) may be considered coherent. In other words, it is the time interval within which its phase is, on average, predictable.… … Wikipedia
Coherence length — In physics, coherence length is the propagation distance from a coherent source to a point where an electromagnetic wave (or wave packet, wave function, etc.) maintains a specified degree of coherence. The significance is that interference will… … Wikipedia
Coherence time (communications systems) — In communications systems, a communication channel may change with time. Coherence time is the time duration over which the channel impulse response is considered to be not varying. Such channel variation is much more significant in wireless… … Wikipedia
Frequency — For other uses, see Frequency (disambiguation). Three cyclically flashing lights, from lowest frequency (top) to highest frequency (bottom). f is the frequency in hertz (Hz), meaning the number of cycles per second. T is the period in seconds (s) … Wikipedia
Coherence (statistics) — In probability theory and statistics, coherence can have two meanings. When dealing with personal probability assessments, or supposed probabilities derived in nonstandard ways, it is a property of self consistency across a whole set of such… … Wikipedia
coherence — /koh hear euhns, her /, n. 1. the act or state of cohering; cohesion. 2. logical interconnection; overall sense or understandability. 3. congruity; consistency. 4. Physics, Optics. (of waves) the state of being coherent. 5. Ling. the property of… … Universalium
