Conflict-Free Vectorized In-order In-place Radix-r Belief Propagation Polar Code Decoder Algorithm
Arvid B. van den Brink, Marco J.G. Bekooij · 2020
A vectorized belief propagation polar code decoder is desirable because of the potentially high throughput and the ability of integration in processors that perform vectorized processing and access wide memory words. However, current state-of-the-art belief propagation polar code decoder algorithms do not perform vector processing and store intermediate results in non consecutive memory locations. Also the current state-of-the-art belief propagation polar code decoders require separate memories to store left and right bound intermediate results.
