| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Spinal codes are a recently proposed rateless code that achieves Shannon capacity on additive white Gaussian noise channel. Some breadth-first tree search algorithms are introduced for decoding spinal codes, how- ever, sorting operations of conventional decoding algorithms remain as critical throughput bottleneck. To achieve higher throughput of the decoder, non-sorting algorithms and highly parallelism are attractive. In this paper, we investigate a property of threshold algorithms for decoding spinal codes, i.e., T-algorithm and metric-based thresh- old algorithm. These algorithms are evaluated from the viewpoints of computational complexity and throughput, and we demonstrate the superiority of threshold decoding algorithms. | |
