A Systematic Construction of LDPC Codes for Relay Channel in Time-Division mode

A Systematic Construction of LDPC Codes for Relay Channel in Time-Division mode

We address the problem of low density parity-check (LDPC) code design for relay channel in time-division mode based on a distributed strategy: In the first time slot, the source transmits part of the codeword. The relay and the destination receive it but only the relay can decode it. In the second t...

description We address the problem of low density parity-check (LDPC) code design for relay channel in time-division mode based on a distributed strategy: In the first time slot, the source transmits part of the codeword. The relay and the destination receive it but only the relay can decode it. In the second time slot, the relay transmits the additional redundant bits to the destination. The destination is able to decode the transmitted codeword based on the data received in both time slots. The asymptotic performance of the LDPC codes that we designed are as close as 0.6 decibel from the theoretical limit.
