Dynamic-list joint detection and decoding of LDPC-coded V-BLAST systems

Soft iterative detection and decoding techniques have been shown to be able to achieve near-capacity performance in multiple antenna systems. To obtain the optimal soft information by marginalizing over the entire observation space is intractable; and it is not clear what the best way to obtain the suboptimal soft information is. In this talk, an improved scheme is proposed which can be adapted to various list-type detectors and provide superior performance.
