| Abstract: | 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 reduces the buffer size of the system by updating the value of offset to the present estimate. A weighted variable is taken for updating the previous offset. Simulations are done for comparing the length of prefix to be used for better estimation accuracy. Results show that the recursive algorithm has better performance than the ML estimator. |
