Abstract: front page image
(EN)An amplifier-less radio architecture provides a system and method for allowing the addition of multiple antennas to radio systems, particularly radio systems in accordance with the Wi-Fi standards, without increasing the complexity, cost, and power consumption of the resulting circuitry. Multiple antennas, directly coupled to transmitters and receivers, enable the combination of received or transmitted signals in such a way as to achieve a quadratic improvement, in a manner not unlike that which would be achieved by an impracticably larger antenna. The invention thus lends itself to fully integrating all necessary radio circuitry into a single low-power, amplifier-less integrated circuit.
(FR)Selon l'invention, une architecture radio moins amplificatrice fournit un système et un procédé pour permettre l'ajout de multiples antennes à des systèmes radio, en particulier des systèmes radio selon les normes Wi-fi, sans augmenter la complexité, le coût, et la consommation de puissance de la circuiterie résultante. De multiples antennes, directement couplées à des émetteurs et des récepteurs, permettent la combinaison de signaux reçus ou émis afin d'obtenir une amélioration quadratique, d'une manière différente de celle qui serait obtenue par une antenne plus grande impraticable. L'invention aide ainsi celle-ci à entièrement intégrer toute la circuiterie radio nécessaire dans un circuit intégré moins amplificateur à faible puissance unique.
