Secant Method based CFO Estimation and Correction for MC-CDMA Systems over Rayleigh Flat Fading Channel

Abstract

In this paper Multi-Carrier Code Division Multiple Access (MC-CDMA) has been proposed as one of the air interface possibility for the fourth era remote correspondence frameworks. Be that as it may, MC-CDMA frameworks endure a great deal of execution corruption because of transporter recurrence balances. In this paper proposes a Numerical Technique dependent on the secant strategy for dazzle Maximum-Likelihood (ML) estimation of transporter recurrence balance in MC-CDMA Systems over Rayleigh level fading channels. The proposed strategy is described by low multifaceted nature and quick union while keeping up the estimation precision.
