  • Patent number: 7313099
    Abstract: A receiver, an integrated circuit chip and a method are provided for estimating the power of a digitally modulated signal received by the receiver in a communication system. The method comprises determining in-phase and quadrature-phase values of a phase constellation system relating to the received signal, calculating at least one modified in-phase value and at least one modified quadrature-phase value relating to the phase constellation system rotated by a predetermined angle, and determining absolute values of the in-phase and quadrature-phase values and the modified in-phase and quadrature-phase values. The method further comprises identifying the maximum of the absolute values, and determining a power estimate of the received signal based on the identified maximum value. The provided technique may allow for estimating the power of a digitally modulated signal in a simple and less complex implementation.

  • Patent number: 6856946
    Abstract: A receiver is provided for receiving a digitally modulated signal in a communication system. The receiver comprises a signal input unit adapted for determining at least one in-phase and at least one quadrature-phase value of the received signal. The receiver further comprises a signal generator connected to receive the in-phase and quadrature-phase values and to generate at least one modified in-phase value and at least one modified quadrature-phase value of a rotated phase constellation system. The receiver further comprises a signal processing unit that is adapted for processing the received signal dependent on the in-phase and quadrature-phase values and the modified in-phase and quadrature-phase values. The signal generator is a passive impedance network. Further, a corresponding integrated circuit chip and operation method are provided. Using a passive impedance network may simplify the hardware implementation by avoiding the need to provide an active amplifier.
