In this paper, a simplified soft-output demapping method is proposed for a coded MIMO-OFDM Wireless LAN system, only requiring 3-bit soft information. In particular, we apply bit-rounding and effective-bit threshold adjustment techniques, in order to effectively extract 3-bit soft information without performance degradation.
