An FPGA Design of Generalized Low-density Parity-check Codes for Rate-adaptive Optical Transport Networks

چکیده
Forward error correction (FEC) is as one of the key technologies enabling the next-generation high-speed fiber optical communications. In this paper, we propose a rate-adaptive scheme using a class of generalized low-density parity-check (GLDPC) codes with a Hamming code as local code. We show that with the proposed unified GLDPC decoder architecture, a variable net coding gains (NCGs) can be achieved with no error floor at BER down to 10, making it a viable solution in the next-generation high-speed fiber optical communications.

FPGA Implementation of Advanced FEC Schemes for Intelligent Aggregation Networks
In state-of-the-art fiber-optics communication systems the fixed forward error correction (FEC) and constellation size are employed. While it is important to closely approach the Shannon limit by using turbo product codes (TPC) and lowdensity parity-check (LDPC) codes with soft-decision decoding (SDD) algorithm; rate-adaptive techniques, which enable increased information rates over short links...

We consider user cooperation in a wireless relay network that comprises a collection of transmitters sending data to a common receiver through inherently unreliable and constantly changing channels. Exploiting the recently developed technology of network coding, we propose a new framework, termed adaptive network coded cooperation (ANCC), as a practical, de-centralized, adaptive and efficient c...
متن کاملDesign of LDPC Decoder Using FPGA: Review of Flexibility
Low Density Parity Check (LDPC) codes have become very popular now-a-days because of their shannon limit approaching error correcting capability and hence have been used in many applications.

This paper proposes an efficient joint secret key encryption-channel coding cryptosystem, based on regular Extended Difference Family Quasi-Cyclic Low-Density Parity-Check codes. The key length of the proposed cryptosystem decreases up to 85 percent using a new efficient compression algorithm. Cryptanalytic methods show that the improved cryptosystem has a significant security advantage over Ra...
