Non-Binary LDPC Code Decoding Algorithms

Non-binary low-density parity-check (LDPC) codes extend conventional binary LDPC schemes by operating over larger Galois fields, affording stronger error-correction ...

Unified C-programmable ASIP architecture for multi-standard Viterbi, Turbo and LDPC decoding

This paper describes an ASIP decoder template suitable for multi-standard Viterbi, Turbo and LDPC decoding. We show architecture fitness for WLAN, WiMAX and 3GPPLTE standards, although various other ...
