چکیده
This paper presents a study on the VHDL implementation of a class of binary irregular structured LDPC codes (IS-LDPC) applied to 100 Gbps optical networks. A comparison between two iterative decoding algorithms for irregular structured LDPC codes, sum-product based on loglikelihood ratio and min-sum, is used to define the best choice for implementation. The performances of IS-LDPC codes are evaluated on an AWGN channel. The aim of this paper is to select out of a class IS-LDPC codes those ones with the best performance using the MS algorithm for VHDL implementation. Index Terms LDPC codes; optical networks; VHDL.

VHDL Design and FPGA Implementation of LDPC Decoder for High Data Rate
In this work, we present a FPGA design and implementation of a parallel architecture of a low complexity LDPC decoder for high data rate applications. The selected code is a regular LDPC code (3, 4). VHDL design and synthesis of such architecture uses the decoding by the algorithm of BP (Believe propagation) simplified "Min-Sum". The complexity of the proposed architecture was studied; it is 63...
متن کاملA Memory Efficient -Fully Parallel QC-LDPC Encoder
Low-Density Parity Check codes are a special class of linear block codes widely used in communication and disk storage systems, due to their Shannon limit approaching performance and their favourable structure. A special class of LDPC codes, called QC-LDPC codes, allows for efficient hardware implementations of encoding and decoding algorithms by exploiting the structure of the Parity Check Mat...

In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...

We present a systematic construction of a class of highrate, well-structured low density parity check (LDPC) codes based on combinatorial designs. We show that the proposed -design results in a class of -regular LDPC codes, which are systematic, quasicyclic, free of length-4 and length-6 cycles, linear-time encodable and decodable, and which have high code rates of .
