基于秩亏傅里叶变换的交替投影编码波形设计
Coded Waveform Design via Alternating Projection Based on Rank Deficient Fourier Transform
摘要
Abstract
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 corre-sponding to different design objects and constraints are defined .The waveform optimization problem is solved via alternating projec-tion .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 ,active interference and range sidelobes .关键词
