Distributed SR-LDPC Codes over Multiple-Access Relay Channel
Rong Xia Sun, Jingwei Liu · 2013
This paper proposes a novel encoding procedure to realize codes that resemble SR-LDPC codes (rate less codes for erasure correction). For the case of two sources communicating with a single destination via a common relay, the two sources separately encode their own symbols of information using SR-LDPC codes. The two code words are then XOR-ed at the relay. The destination can recover the information from the two sources.
