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

Pulse shaping — In digital telecommunication, pulse shaping is the process of changing the waveform of transmitted pulses. Its purpose is to make the transmitted signal suit better to the communication channel by limiting the effective bandwidth of the… … Wikipedia
Amplitude-shift keying — (ASK) is a form of modulation that represents digital data as variations in the amplitude of a carrier wave.The amplitude of an analog carrier signal varies in accordance with the bit stream (modulating signal), keeping frequency and phase… … Wikipedia
Nyquist ISI criterion — Raised cosine response meets the Nyquist ISI criterion. Consecutive raised cosine impulses demonstrate the zero ISI property between transmitted symbols at the sampling instants. At t=0 the middle pulse is at its maximum and the sum of other… … Wikipedia
Ultra-wideband — (aka UWB, ultra wide band, ultraband, etc.) is a radio technology that can be used at very low energy levels for short range high bandwidth communications by using a large portion of the radio spectrum. UWB has traditional applications in non… … Wikipedia
Heaviside condition — The Heaviside condition, due to Oliver Heaviside (1850–1925), is the condition an electrical transmission line must meet in order for there to be no distortion of a transmitted signal. Also known as the distortionless condition, it can be used to … Wikipedia
