SVD-based Blind Estimation of M-Sequence with Modulated DS-CDMA Signals

摘要

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 m-sequence 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.
