Contribution
The paper proposes spatially coupled repeat-accumulate codes with advantages over spatially coupled LDPC codes, including simpler encoders and higher code rates.
Findings
Simpler encoders for the proposed codes
Higher code rates than comparable spatially coupled LDPC codes
Similar decoding thresholds and complexity
Abstract
In this paper we propose a new class of spatially coupled codes based on repeat-accumulate protographs. We show that spatially coupled repeat-accumulate codes have several advantages over spatially coupled low-density parity-check codes including simpler encoders and slightly higher code rates than spatially coupled low-density parity-check codes with similar thresholds and decoding complexity (as measured by the Tanner graph edge density).
