Abstract:
|
We address the problem of 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. |
