- W2393076182 abstract "To analyze the parameter estimation performance of PARAFAC decomposition under Constant-Modulus(CM) constraint,Cramer-Rao Bound(CRB) expressions for PARAFAC decomposition under First Row Known and CM constraints were proposed.The fitting algorithm,named TALS-CM,was also developed.Simulation results showed that,compared to the normal PARAFAC decomposition,CM constrained PARAFAC decomposition has a lower CRB.The performance of TALS-CM algorithm was close to its CRB,which implied that TALS-CM is asymptotically efficient.TALS-CM algorithm has better performance than traditional TALS algorithm.Utilizing CM property of source signal improved the performance of the PARAFAC-based signal processing algorithms." @default.
