A New Algorithm for Finding Minimum-Weight Words in Large Linear Codes
An algorithm for finding small-weight words in large linear codes is developed and a precise analysis of its complexity is given. It is in particular able to decode random [512,256...

Cooperative Uplink of Two Mobile Stations with Network Coding Based on the WiMax LDPC Code
We consider the uplink of two mobile stations with the help of one common relay. Recently, joint network-channel coding based on LDPC codes was proposed for this setup where the ch...

A Non-differential Distributed Space-Time Coding for Partially-Coherent Cooperative Communication
In a distributed space-time coding scheme, based on the relay channel model, the relay nodes co-operate to linearly process the transmitted signal from the source and forward them ...

Expander Codes
Sipser and Spielman have introduced a constructive family of asymptotically good linear error-correcting codes--expander codes--together with a simple parallel algorithm that will ...
