- Abstract
An efficient algorithm is proposed to estimate the parameters of multicomponent cubic phase signals with different amplitudes. This algorithm is based on the product generalized cubic phase function (PGCPF) and the product cubic phase function (PCPF), which are used to compute the cubic phase coefficient and chirp rate of the cubic phase signal, respectively. The parameters of the component with the strongest amplitude are estimated firstly. Then filtering out the strongest component, the parameters of other components in the residual signal are estimated one by one until all of the signal components have been estimated. Computer simulations are carried out to illustrate the effectiveness of the proposed algorithm.
