Abstract :
An accurate signal-to-noise ratio (SNR) measurement is essential for cellular and satellite communication receivers for various purposes, including the demodulation algorithm adaptation to the time-varying channel conditions. In this paper, computationally simple SNR estimation methods, called the error vector magnitude (EVM) method and the minimum mean-square error estimation (MMSE) method are proposed. Analytic derivations as well as simulation results are presented to demonstrate the performance of the proposed schemes
