Optimal LLR Clipping Levels for Mixed Hard/Soft Output Detection
Abstract—Consider a communications system where the detector generates a mix of hard and soft outputs, which are then fed into a soft-input channel decoder. In such a setting, it...

EXIT Chart Evaluation of a Receiver Structure for Multi-User Multi-Antenna OFDM Systems
— In this paper we evaluate, by means of Extrinsic Information Transfer (EXIT) charts, an iterative receiver that has emerged as a promising candidate for non-coherent multi-user...

Mapping for Iterative MMSE-SIC with Belief Propagation
Abstract— In Multiple-Input Multiple-Output (MIMO) wireless systems, since different signals are transmitted by different antennas simultaneously, interference occurs between the...
