A novel LDPC decoder for DVB-S2 IP
Abstract—In this paper a programmable Forward Error Correction (FEC) IP for a DVB-S2 receiver is presented. It is composed of a Low-Density Parity Check (LDPC), a Bose-ChaudhuriH...

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...

Subspace tracking of fast time-varying channels in precoded MIMO-OFDM systems
This paper presents a blind subspace-based tracking scheme for precoded MIMO-OFDM systems over rapidly time-varying wireless channels. Subspace-based tracking is normally consider...
