- Abstract:
- The paper shows a new algorithm for the phase noise measurement. The algorithm is based on the constellation examination of the IQ plane of the single carried digital modulated signal. It can be used to measure the phase noise both on the carrier signal and on the demodulated signal. Advantages of the proposed algorithm are: (i) the number of samples in practice does not affects the error, (ii) the percentage error is reduced if compared with other methods, and (iii) the phase noise shape weakly affects the error. The paper provides the theoretical background and reports the results of numerical experiments that validate the proposed algorithm.
