A novel recursive algorithm for estimating the carrier frequency offset (CFO) is presented which is compared against a basic maximum likelihood (ML) algorithm for orthogonal frequency division multiplexing (OFDM) scheme. Cyclic prefix (CP) is used for estimating the offset which enables the estimation without additional sequences. The recursive algorithm(More)
As the Power Line Communication (PLC) network standard, IEEE 1901 uses OFDM for its uplink and downlink transmissions, the sensitivity of the network to the timing and frequency errors are prominent. The frequency errors are due to the carrier frequency offsets caused by instabilities in local oscillators and ageing effects. A novel recursive algorithm for(More)
