Novel Joint Blind Channel and Carrier Offset Estimation Method for CDMA Systems

In this paper a novel joint blind channel estimation and carrier offset method for code division multiple access (CDMA) is proposed. The new method combines singular value decomposition (SVD) analysis with carrier-offset parameter, which was not taken into account previously in the matrix power method. The simulation results obtained from the proposed scheme show that a better performance is achieved compared with other schemes in the literature. Also, the computational cost is much lower compared with other schemes because the mathematical model is independent of the need of knowledge of the noise subspace.
