Exploiting cyclic prefix for joint detection, decoding and channel estimation in OFDM via EM algorithm and message passing

This paper considers the coded OFDM system and instead of discarding the cyclic prefix (CP) at the receiver, we utilize the CP observation for joint detection, decoding and channel estimation. In particular, detection and decoding are performed iteratively between an equalizer and a soft-input soft-...
