Although error-prone patterns have been extensively studied for low-density parity-check (LDPC) codes, to the best of our knowledge, they have never been fully explored for Fountain codes. It is shown that dominant trapping sets of Fountain codes are the absorbing sets. They happen in the so-called error floor, corresponding to a significant flattening in(More)
This paper addresses throughput and delay gains resulting from network coding (NC) used to complement multi-packet reception (MPR) in a single-relay multi-user wireless network in saturated and non-saturated traffic conditions. The cross-layer analytical framework is presented in analyzing the performance of the encode-and-forward (EF) relaying wireless(More)
Error-prone patterns have been extensively studied for low-density parity-check codes yet they have never been fully explored for generator-based ‘Fountain codes’. It is shown here that these phenomena are related to certain combinatorial structures within the Tanner graph (TG) representation of the code, previously termed absorbing sets. The authors(More)
