Thus the SYN CN processing is the first hardware aware algorithm for NB- LDPC decoding, enabling low latency and high throughput decoder architectures.. The paper is structured

Bubble check: a simplified algorithm for elementary check node processing in extended min-sum non-binary LDPC decoders... Bubble check: a simplified algorithm for elementary check

reviews NB-LDPC decoding with particular attention to the Min-Sum and the EMS algorithms. Section III is dedicated to the global decoder architecture and its scheduling. The

Furthermore, we present the first hardware architectures for the computational units of the Local-SOVA algorithm, namely the add-compare select unit and the soft output unit of

We give a bound on the number of polynomials of degree d in a Gr¨obner basis computed by Faug`ere’s F 5 algorithm (2002) in this generic case for the grevlex ordering (which is also

Among other results, we show that a Turing spectrum can be realized via a subshift of linear complexity if and only if it consists of the union of a finite set and a finite number

We conclude the paper in section VIII- A by a fair comparison between the proposed non-binary decoding algorithm and the binary corrected Min-Sum (MS) algorithm [10] applied to

This article brings new complexity results for computing subresultant polynomials over commutative rings endowed with the partially dened division routine.. We design a divide
