Compute-and-forward relaying (CAF) is effective to increase bandwidth efficiency of wireless two-way relay channels. In CAF, a relay tries to decode a linear combination of transmitted messages from other terminals or relays. In this paper, we will present an asymptotic performance analysis on spatially-coupled LDPC codes over two-way relay channels based on density evolution (DE). Because of the asymmetric nature of the channel, we use the population dynamics DE combined with DE formulas for asymmetric channels. The results indicate that the spatial coupling codes yield improvements in the BP threshold compared with corresponding uncoupled codes for two-way relay channels. |
