Complexity-scalable H.264/AVC in an IPP-based video encoder
Real-time high-definition video encoding is a computationhungry task that challenges software-based solutions. For that, in this work we adopted an Intel software implementation o...

Iterative Sparse Channel Estimation and Decoding for Underwater MIMO-OFDM
In this paper we propose a block-by-block iterative receiver for underwater MIMO-OFDM that couples channel estimation with MIMO detection and channel decoding. In particular, the c...
