Phase system rotation for power estimation |
摘要 |
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.
