Comprehensive recognition algorithm of RS code based on fast code root trial

open access: yesTongxin xuebao, 2022
In order to solve the problem of high computation and high missed alarm probability of RS (Reed-Solomon) codes for recognition, comprehensive recognition algorithm of RS codes based on fast code root trial was proposed.Firstly, the check relationship was

Modified Welch Berlekamp Algorithm to Decode Reed Solomon Codes

open access: yesMATEC Web of Conferences, 2018
In this paper, the Reed Solomon Code is decoded using the Welch-Berlekamp Algorithm. The RS Decoder is implemented using Hardware Description Language VHDL (VHSIC hardware Description Language) and simulated on Modelsim software.

An Efficient CDMA System Based on Reed Solomon Code (RS Code)

open access: yes, 2018
Accurate Error control is a necessary constraint for the design of Cellular Code Division Multiple Access (CDMA) systems. The Block codes can correct twice as many erasures as errors; the coded performance can be improved. In this paper, we propose ‘An efficient Error correcting coding in CDMA systems. The system performance is improved using FEC based

The Dimension of Subcode-Subfields of Shortened Generalized Reed Solomon Codes

open access: yes, 2011
Reed-Solomon (RS) codes are among the most ubiquitous codes due to their good parameters as well as efficient encoding and decoding procedures. However, RS codes suffer from having a fixed length.

Throughput analysis of nonbinary type-II hybrid ARQ [PDF]

open access: yes, 2003
Nonbinary type-II hybrid ARQ (HARQ), which combines shortened Reed-Solomon (RS) code with ARQ, is proposed. Its throughput is obtained by extending Lin and Yu's analysis of binary type-II HARQ.

Repairing Reed-Solomon Codes

open access: yes, 2016
We study the performance of Reed-Solomon (RS) codes for the \em exact repair problem \em in distributed storage. Our main result is that, in some parameter regimes, Reed-Solomon codes are optimal regenerating codes, among MDS codes with linear repair ...
