Résumé

The Chong-Motani-Garg inner bound for the two-user interference channel is generalized to a special case of many-user interference channels. By taking a geometric viewpoint and using rate-splitting arguments, it is shown that all operating points in the Chong-Motani-Garg inner bound allow decoding by successive cancellation at all receivers.

Channel access method

In telecommunications and computer networks, a channel access method or multiple access method allows more than two terminals connected to the same transmission medium to transmit over it and to share its capacity. Examples of shared physical media are wireless networks, bus networks, ring networks and point-to-point links operating in half-duplex mode. A channel access method is based on multiplexing, that allows several data streams or signals to share the same communication channel or transmission medium.

Cyclic prefix

In telecommunications, the term cyclic prefix refers to the prefixing of a symbol with a repetition of the end. The receiver is typically configured to discard the cyclic prefix samples, but the cyclic prefix serves two purposes: It provides a guard interval to eliminate intersymbol interference from the previous symbol. It repeats the end of the symbol so the linear convolution of a frequency-selective multipath channel can be modeled as circular convolution, which in turn may transform to the frequency domain via a discrete Fourier transform.

Atténuation du signal

vignette|296x296px|L'atténuation du signal en fonction de la fréquence et du temps laisse apparaître un motif nuageux sur un spectrogramme. Le temps est représenté sur l'axe horizontal, la fréquence sur l'axe vertical. L'intensité du signal apparaît en niveaux de gris. Dans les transmissions sans fil, l'atténuation du signal ou évanouissement (fading) est la variation de la puissance du signal causée par plusieurs variables. Ces variables incluent le temps, la position géographique et la fréquence.
