5g-nr-ldpc
This library implements a basic version of the 5G NR LDPC code as specified in TS38.212. The decoder implements the sum-product algorithm and is based on [1].
Quick start
The file ldpcExample.m provides a minimal working example of encoding and decoding.
Features
So far the implementation supports the block lengths N=[264, 544, 1056, 2176, 4224, 8448] and code rates R=[1/3, 1/2, 2/3, 3/4, 5/6]. Note that the development is not finished. Extension to more code rates and other block lengths are easily possible. The implementation includes the base graphs 1 and 2.
