This paper describes the implementation of a library that aims to process the decoding of a 5G signal using the LDPC algorithm. During the implementation of the algorithm, several optimizations will be adopted to reduce the number of iterations required for the complete decoding of the received data and reduce the power consumption. In addition to the algorithm’s implementation, it will also be necessary to implement blocks that manage the transfer from an external block to the one in which the decoding will be processed. In this case, too, several optimizations will be carried out to reduce power consumption.
