FPGA based High Bandwidth LDPC using a Channel Coding Technique

Abstract

Error-correcting codewords using Low-Density Parity Check (LDPC) have been the subject of many studies in the communications field. Because of their excellent error correction performance, low-complexity calculations, and appropriateness for parallel hardware design, they have also become typical digital modulation schemes in various protocols. Meanwhile, a lot of effort has gone into developing LDPC decoders that take advantage of the high processor speed and parallel processing of Field-Programmable Gate Array (FPGA) devices, which are now a viable alternative to Application-Specific Integrated Circuit (ASIC) systems for LDPC decoder implementations. However, the open literature FPGA-based LDPC encoder solutions differ widely in design choices and quality criteria, making them hard to compare and much more challenging to execute. A corrected signal decoding method with several design optimizations that lower the expenses of supporting several different codes The decoder's development findings show that it can achieve better bandwidth utilization than earlier flexible FPGAbased LDPC decoders while still meeting the requisite amount of extensibility and satisfactory error-correcting effectiveness.
