ABSTRACT:
A method and apparatus is disclosed herein for adaptive MaclogMAP-type receiver structures. In one embodiment, a device comprises a receiver to receive information-bearing signals from the transmitter wirelessly transmitted using OFDM and bit interleaved coded modulation, and the receiver comprises an inner decoder structure having a multiple-in multiple-out (MIMO) joint demapper to perform most likely transmitted symbol estimation using a modified MaxLogMAP process that is operable to adapt a degree of metric correction based on quality of OFDM tones.
