pulse time modulation — noun : modulation of the time intervals between successive pulses of constant duration and amplitude in accordance with a signal; specifically : a system of multiplex high frequency transmission using this method of modulation … Useful english dictionary
Modulation space — Modulation spaces[1] are a family of Banach spaces defined by the behavior of the short time Fourier transform with respect to a test function from the Schwartz space. They were originally proposed by Hans Georg Feichtinger and are recognized to… … Wikipedia
Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… … Wikipedia
Time-frequency analysis — is a body of techniques for characterizing and manipulating signals whose component frequencies vary in time, such as transient signals.Whereas the technique of the Fourier transform can be used to obtain the frequency spectrum of a signal whose… … Wikipedia
Frequency-division multiplexing — (FDM) is a form of signal multiplexing where multiple baseband signals are modulated on different frequency carrier waves and added together to create a composite signal. Non telephoneFDM can also be used to combine multiple signals before final… … Wikipedia
Frequency-hopping spread spectrum — (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. A spread spectrum transmission offers three main advantages over… … Wikipedia
