Spatially Coupled Protograph-Based LDPC Codes for Decode-and-Forward in Erasure Relay Channel
نویسندگان
چکیده
We consider spatially-coupled protograph-based LDPC codes for the three terminal erasure relay channel. It is observed that BP threshold value, the maximal erasure probability of the channel for which decoding error probability converges to zero, of spatially-coupled codes, in particular spatially-coupled MacKay-Neal code, is close to the theoretical limit for the relay channel. Empirical results suggest that spatially-coupled protograph-based LDPC codes have great potential to achieve theoretical limit of a general relay channel. key words: Spatially coupled codes, Protograph-based LDPC codes, Relay, Erasure channel

Notes: Finite-length Protograph-based Spatially Coupled LDPC Codes
The finite-length performance of multi-edge spatially coupled low-density parity-check (SC-LDPC) codes is analyzed over the binary erasure channel (BEC). Existing scaling laws are extended to arbitrary protograph base matrices including puncturing patterns and multiple edges between nodes. Compared to more involved rate-1/2 structures proposed to improve the threshold to minimum distance trade-...
متن کاملPerformance Analysis of Protograph LDPC Codes for Nakagami-$m$ Fading Relay Channels
In this paper, we investigate the error performance of the protograph (LDPC) codes over Nakagamim fading relay channels. We first calculate the decoding thresholds of the protograph codes over such channels with different fading depths (i.e., different values of m) by exploiting the modified protograph extrinsic information transfer (PEXIT) algorithm. Furthermore, based on the PEXIT analysis an...
متن کاملPolarization of Multi-Relay Channels: A Suitable Method for DF and CF Relaying with Orthogonal Receiver
Polar codes, that have been recently introduced by Arikan, are one of the first codes that achieved the capacity for vast numerous channels and they also have low complexity in symmetric memoryless channels. Polar codes are constructed based on a phenomenon called channel polarization. This paper discusses relay channel polarization in order to achieve the capacity and show that if inputs of tw...
متن کاملAsymptotic Analysis on Spatial Coupling Coding for Two-Way Relay Channels
Compute-and-forward relaying is effective to increase bandwidth efficiency of wireless two-way relay channels. In a compute-and-forward scheme, a relay tries to decode a linear combination composed of transmitted messages from other terminals or relays. Design for error correcting codes and its decoding algorithms suitable for compute-and-forward relaying schemes are still important issue to be...
متن کاملStructured LDPC convolutional codes
LDPC convolutional codes, also known as spatially coupled LDPC codes, have attracted considerable attention due to their promising properties. By coupling the protographs from different positions into a chain and terminating the chain properly, the resulting convolutional-like LDPC code ensemble is able to produce capacityachieving performance in the limit of large parameters. In addition, opti...
