摘要: A method is provided for processing received data symbols in an orthogonal frequency division multiplexing (OFDM) transmission scheme, and OFDM baseband receiver which performs this method, order to support selective noise estimation, especially interference limited environments, offer improved estimation performance reduced computational complexity. This achieved by determining time levels of combined interference, computing normalization values a respective time-frequency region the plane that applies scheme employed, from said plus levels, applying obtain normalized symbols, channel estimates, communication parameter estimates demodulated decoded using estimates.
