Energy-saving method for the wireless reception of data modulated on a carrier signal
Abstract:
An energy-saving method for wireless reception of data modulated on a carrier signal is carried out in a receiver circuit including a first group and a second group of circuit elements. The first group of the circuit elements required for recovering the data from the modulated carrier signal are supplied intermittently with electrical energy, while the remaining circuit elements of the second group are supplied with uninterrupted electrical energy. After an intermittent unpowered phase without electrical energy being supplied to the first group of circuit elements, the receiver can be operated in the next intermittent powered phase of the second group of circuit elements with parameters that determined the receiver properties which were present in the last reception phase and that have been stored, thus eliminating the time required for renewed tuning in.
