Half-Duplex Relaying With Serially-Concatenated Low-Density Generator Matrix (SCLDGM) Codes

Recently, the integration of cooperation with coding has proven to be a very useful technique to enhance relay system performance. Relay systems based on Low-Density Parity Check (LDPC) codes have the potential to approach the theoretical information limits very closely. However, LDPC codes have a disadvantage in that the encoding complexity is high. To solve this problem, Serially-Concatenated Low-Density Generator Matrix (SCLDGM) codes are attracting attentions due to its low encoding complexity. However, the performance of SCLDGM coded relaying has not been investigated.
