A high throughput configurable partially-parallel decoder architecture for Quasi-Cyclic Low-Density Parity-Check Codes

Abstract: In this paper, we are proposing a new architecture for the fast decoding of Quasi-Cyclic Low-Density Parity Codes (QC-LDPC). QC-LDPC codes are becoming more and more popular in a wide range of applications, including data transmission (WiMAX, DVB-S2) in telecommunication systems, increasing the need for effective decoder architectures. In the present approach, support for a large subset of QC-LDPC codes is provided thanks to the configurability of the architecture at the synthesis level. High levels of paralle… Show more

“…Considering a coding rate equal to 0.9, full-parallel hardware architecture [32] is too complex to be implemented for the fronthaul link in the C-RAN context. Since we are seeking for low-latency and highthroughput circuit, partially parallel architecture is recommended here [33][34][35][36]. In this section, we will put the emphasis on GDBF and BWGDBF implementation architectures.…”
