Batteriebetriebene Funkempfänger, die durch reduzieren der aktiven Empfangszeit Strom sparen |
摘要 |
A battery-powered portable radio receiver and a method of operating the battery-powered radio receiver during Standby Mode in order to decrease battery-current drain is provided. In Standby Mode, a receive path of the radio receiver is activated during a data-detection time interval for the detection of data destined for selected receivers, and a preconditioning time interval for performing pre-conditioning functions with respect to the receiver before the data-detection time interval. The method includes: (a) activating the receive path at a predetermined time instant before the start of the data-detection time interval to perform the pro-conditioning functions with respect to the receiver, (b) detecting a predetermined characteristic of the received signal affected by each of the pre-conditioning functions; (c) comparing each of the predetermined characteristics with e threshold; (d) where the predetermined characteristics are within their respective thresholds, deactivating the receive path until the start of the data-detection time interval, and then reactivating the receive path fur the data-detection time interval; and (e) where the predetermined characteristics are outside their respective thresholds, continuing the pre-conditioning functions until the predetermined characteristics are within their respective thresholds, then deactivating the receive path until the start of the data-detection time interval, and then reactivating the receive path for the data-detection time interval. |
