A method is presented to design constant modulus waveforms with low magnitude of power spectral density and autocorrelation in desired intervals.The waveform design problem is transformed into a phase retrieval one
and three sets corresponding to different design objects and constraints are defined.The waveform optimization problem is solved via alternating projection.According to the relationship between the covariance matrix and the power spectral density of the colored noise
the projector used in the algorithm is implemented efficiently based on fast Fourier transformation.Thus the computational efficiency is improved.Finally
the numerical simulations demonstrate the effectiveness of this algorithm.The waveforms designed by this algorithm can be used in radar
sonar
and wireless communication systems to suppress colored noise
