Abstract :
We consider the problem of separating two constant-amplitude continuous-phase signal components overlapping in time and frequency band. The discrete polynomial-phase transform (DPT) is used to estimate the parameters of the phase function of each component. Simulations are used to evaluate the performance of the algorithm
