Passive impedance network for rotating a phase system |
摘要 |
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.
