摘要
In an OFDM (Orthogonal frequency-division multiplexing) communication system, a receiver comprising an inner forward error correction device, or an inner forward error correction device is provided. Either the inner forward error correction device, or the outer forward error correction device comprises an improved method for deriving a bit log-likelihood ratio derived from a symbol log-likelihood ratio. The method includes the steps of: providing two simplified parameters; and using the two simplified parameters in addition and subtraction only to derive the bit log-likelihood ratio derived from the symbol log-likelihood ratio.
