Abstract
A low-complexity blind algorithm is presented for estimating the Signal-to-Noise ratio (SNR) of an Orthogonal Frequency Division Multiplexing (OFDM) signal transmitted over a frequency-selective channel with colored or white noise. The algorithm only uses the second moment statistics in the frequency domain without requiring training symbols or pilot subcarriers.
