Abstract: Recently, density evolution techniques have been used to predict the performance of iterative decoders utilizing the sum-product belief propagation algorithm. We extend this analysis to the ...

Abstract: In this paper, an improved low-complexity sum-product decoding algorithm is presented for low-density parity-check (LDPC) codes. In the proposed algorithm, reduction in computational ...

本連載の第1回ではLDPC符号の基礎とパリティ検査行列が2部グラフで表現できることを概観した。今回は，LDPC符号の有効性の鍵である復号法に焦点を絞り，LDPC符号の誤り訂正の原理，そしてsum-productアルゴリズムの詳細について説明する。 sum-product ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

You can enable the self-corrected update for any of the above listed algorithms to further boost its decoding performance. It works by erasing unreliable bit nodes ...

January 6, 2025 - Global IP Core Sales - In the Sum Product Algorithm (SPA) for LDPC decoding the messages are sent from the check nodes to bit nodes after the SPA steps which are (for one iteration): ...
