Abstract
A digital broadband broadcast receiver is configured to receive bits transmitted in transmission symbols, such as orthogonal frequency division multiplexing (OFDM) symbols. The reliability of the received bits is scaled with a non-linear scaling function which is in relation to the amount of interfered part of a received transmission symbol. In the scaling, a burst state information (BSI) and/or channel state information (CSI) method can be used.
