Title
High throughput LDPC code and decoder design for HINOC 2.0 systems
Abstract
This paper presents a high-throughput structured low density parity check (LDPC) code and an optimal parallel decoder architecture with advanced Ping-Pong RAMs for the HINOC 2.0 systems. An additional iteration scheme is proposed to further improve decoding performance by taking full use of time intervals of the discontinuous streams, an important feature in HINOC 2.0 systems. The proposed LDPC code proves to be of better performance than the codes adopted in the current standards (802.16e). The proposed decoder is implemented and synthesized on FPGA Stratix V, with the maximum working frequency of 145MHz. The total resource cost is reduced by 23%, which is the cost of one decoder core, with slightly increased complexity in control logics, compared with the traditional Ping-Pong RAM based parallel architecture. The resulting performance is 2Gbps which is enough to support HINOC 2.0 systems.
