Patent

CA 2338470

Methods, systems and computer program products are provided which control the operation of a receiver of a wireless device so as to reduce the power consumption of the receiver by setting the third order intercept point of a low noise amplifier based upon at least one of a strength of a signal received by the wireless device or a transmission power of a transmitter of the wireless device. Furthermore, the gain of the low noise amplifier may also be set based upon received signal strength or transmitter power. Also, the gain of an amplifier associated with a mixer of the receiver may be set based upon received signal strength or transmitter power. Preferably, multiple power modes are provided to tailor the power consumption to the operating conditions of the wireless device.

L'invention concerne des procédés, systèmes et progiciels qui commandent le fonctionnement d'un récepteur d'un dispositif sans fil, de manière à réduire la consommation d'énergie de ce dernier par le réglage du point d'interception de troisième ordre d'un amplificateur à faible bruit en fonction d'au moins l'intensité d'un signal reçu par le dispositif sans fil ou la puissance de transmission dudit dispositif sans fil. Par ailleurs, le gain de l'amplificateur à faible bruit peut également être réglé en fonction de l'intensité du signal reçu ou de la puissance de l'émetteur. De plus, le gain d'un amplificateur associé à un mélangeur du récepteur peut être réglé en fonction de l'intensité du signal reçu ou de la puissance de l'émetteur. De préférence, de multiples modes sont prévus de manière que la consommation d'énergie puisse être adaptée aux conditions de fonctionnement du dispositifs sans fil.
