A Message-Passing Receiver for BICM-OFDM over Unknown Clustered-Sparse Channels
We propose a factor-graph-based approach to joint channel-estimationand-decoding of bit-interleaved coded orthogonal frequency division multiplexing (BICM-OFDM). In contrast to ex...

Improving message passing over Ethernet with I/OAT copy offload in Open-MX
Abstract--Open-MX is a new message passing layer implemented on top of the generic Ethernet stack of the Linux kernel. Open-MX works on all Ethernet hardware, but it suffers from e...
