SVD-based Blind Estimation of M-Sequence with Modulated DS-CDMA Signals
Yu Han, Lei Shen, Jia-Jia Miao · 2017
An Singular Value Decomposition (SVD) based method was proposed and developed in this work to estimate the m-sequence of modulated Direct-Sequence Code Division Multiple Access (DS-CDMA) signals with carrier frequency offset.By building eigenvalues based objections, a proper carrier frequency range can be determined, so that the msequence can be blindly estimated by SVD in this carrier frequency range.Closed-form models and simulation results suggest that the proposed method is efficient in modulating signals.
