| Abstract: | To investigate the parameters estimation of Frank coded signal in nonc
ooperative condition, an averaged cyclic periodogram based cyclic spectral featu
res estimation algorithm is proposed. The connection between signal parameters a
nd cyclic spectral features is utilized to estimate the key parameters of Frank
coded signal. The amount of calculation and the process of the algorithm is give
n and analysed. The normalized RMS error(NRMSE) of estimation is measured to an
alyse the influence of the noise on parameters estimation and verify the validit
y of the algorithm. |
