Abstract :
We present a new PLNC scheme based on the recently developed compute-and-forward (C&F) paradigm and low density lattice codes (LDLC). LDLC possesses high coding gain and good algebraic structure which is inherently suitable for C&F. We also show that the ring-based constellation can be used to improve the average rate per dimension.
