Hardware Optimization for Belief Propagation Polar Code Decoder with Early Stopping Criteria Using High-Speed Parallel-Prefix Ling Adder
Simsek, Cemaleddin; Turk, Kadir (IEEE, 2017)Belief propagation (BP) polar code decoder is well-studied from many aspects. This study proposes a hardware optimization to improve performance of polar BP decoder by modifying both processing element (PE) and early ... -
Low-Complexity Early Termination Method for Rateless Soft Decoder
Albayrak, Cenk; Simsek, Cemaleddin; Turk, Kadir (IEEE-Inst Electrical Electronics Engineers Inc, 2017)We propose a new early termination method (ETM) with low computational complexity for Luby transform belief propagation (BP) decoder. The proposed method, which we call least reliable messages (LRM) ETM, observes only sign ... -
Performance of Visible Light Communication with Colour Shift Keying Modulation and Polar Code
Simsek, Cemaleddin; Tugcu, Emin; Albayrak, Cenk; Yazgan, Ayhan; Turk, Kadir (IEEE, 2018)Visible light communication (VLC) is an emerging technology to fulfill both illumination and communication purposes considered as either an alternative or a support system for some of scenarios carried by RF communication ... -
Sign Alterations of LLR Values Based Early Termination Method for LT BP Decoder
Albayrak, Cenk; Simsek, Cemaleddin; Turk, Kadir (IEEE, 2017)In this letter, a new early termination method is proposed for Luby transform (LT) belief propagation (BP) decoder. The proposed method is decided whether BP decoder output converges to original data bits by observing only ... -
Simplified Early Stopping Criterion for Belief-Propagation Polar Code Decoders
Simsek, Cemaleddin; Turk, Kadir (IEEE-Inst Electrical Electronics Engineers Inc, 2016)As the first theoretically proven capacity-achieving error correction code, polar codes have become a milestone in information theory field, which draw serious attention by its low complexity encoding and decoding structures. ...
