Mechanism of interchange between the reflections in a channel of communications with the power spectral density
The theoretical limit given by the Shannon Capacity equation has been the origin of communications systems based on the interchange between bandwidth and power. This article explores the interchange between the power spectral density and the reflections that can be generated in a communications chan...

Este artículo explora el intercambio entre la densidad espectral de potencia y las reflexiones que se pueden generar en un canal de comunicaciones, con el fin último de poder disminuir la densidad espectral de potencia para una misma capacidad. Las reflexiones pueden ser expresadas como un número de reflexiones controladas o mediante un coeficiente de reflexión. Los canales estudiados muestran que este intercambio es posible. Se encontró un nuevo modelo basado en circuitos realimentados para representar una línea de transmisión, el cual resultó útil para estudiar el canal MISO formado por varias líneas de transmisión de diferente longitud. Además se estudió un modelo de dispersión elíptica geométrica para representar un canal SISO.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ingenieríahttps://revistas.unal.edu.co/index.php/ingeinv/article/view/58049Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónCárdenas, José Roberto (2017) Mechanism of interchange between the reflections in a channel of communications with the power spectral density.

The theoretical limit given by the Shannon Capacity equation has been the origin of communications systems based on the interchange between bandwidth and power. This article explores the interchange between the power spectral density and the reflections that can be generated in a communications channel, with the ultimate aim of being able to decrease the power spectral density for the same capacity. The reflections can be expressed as a number of controlled reflections or by a reflection coefficient. The channels studied show that this exchange is possible. A new model based on feedback circuits was found to represent a transmission line, which was useful to study the MISO channel formed by several transmission lines of different length. A geometric elliptic dispersion model to represent a SISO channel was studied too. |
