Blind Recursive Tracking of Carrier Frequency Offset (CFO) Vector in MC-CDMA Systems

A recursive algorithm for estimating and updating the effective carrier frequency offset (CFO) vector in a multicarrier code-division multiple-access (MC-CDMA) system is proposed in this work. The recursive relation is derived based on the expectation maximization (EM) algorithm with a quadratic con...
