TC5100 is a highly flexible LDPC encoder/decoder Core. It can essentially cover all possible quasi-cyclic LDPC codes: WiFi, WiMAX, proprietary codes, and also 3GPP Next Release (5G NR) candidate codes. The Core implements a comprehensive set of features like rate matching and HARQ combining. Several Gbps are typically reached by the decoder, tens of Gbps for the encoder. The Core is ideally suited for pre-5G systems, proprietary extensions of WiFi - based links, or any application where flexibility is a key aspect.
