Front-End Estimation of Noise Power and SNR in OFDM Systems

Abstract - In this paper a front-end Noise Power and SNRestimation method based on one OFDM preamble is proposed and compared with previously published SNR estimators – none of which are front-end estimator. The estimator makes use of two identical halves property of time synchronization preamble u...
