WebJul 22, 2024 · This paper proposes a new decoding algorithm for systematic RS codes taking the modular approach as the key equation solver, and shows that when decoding practical RS codes, the new algorithm is significantly superior to the existing methods in terms of computational complexity. Decoding algorithms for Reed–Solomon (RS) codes … WebThe Reed-Solomon code, like the convolutional code, is a transparent code. This means that if the channel symbols have been inverted somewhere along the line, the decoders will still operate. The result will be the complement of the original data. However, the Reed-Solomon code loses its transparency if virtual zero fill is used.

WebAug 7, 2024 · The result is: p(x) = 23 6 x3 + 9 2x2 + 22 3 x + 3. Note how some of the coefficients of p(x) are rational numbers instead of integers. This is one of the reasons why integers shouldn’t be used for Reed-Solomon coding! Evaluating p(x) for x values of 3 and 4 gives 44 and 147.

WebThe results of "Reed-Solomon Coding Part II – Punctures" correspond to a system with erasures and punctures. From the curves, observe that the channel BER is worse with shortening because the coded Eb/N0 is worse. This degraded coded Eb/N0 occurs because the code rate of the shortened code is much lower than that of the nonshortened code.
