On the Parallelism of Convolutional Turbo Decoding and Interleaving Interference
— In forward error correction, convolutional turbo codes were introduced to increase error correction capability approaching the Shannon bound. Decoding of these codes, however, is an iterative process requiring high computation rate and latency. Thus, in order to achieve high throughput and to reduce latency, crucial in emerging digital communication applications, parallel implementations become mandatory. This paper explores and analyses existing parallelism techniques in convolutional turbo decoding with the BCJR algorithm. For component-decoder parallelism, we illustrate the influence of interleaving scheme and we propose new interleaving rules allowing to maximize parallelism efficiency.
