Ordered statistics decoding
WebAs a kind of maximum-likelihood decoding algorithm, ordered statistics decoding (OSD) can be applied with classical strong channel codes, e.g. BCH codes and Reed-Solomon codes, … WebThe OSD decoding algorithm with parameter L (OSD- L) has three steps. First, sort the columns of G according to the absolute value of the vector Y which is received from the channel. Second, find the K most reliable independent columns of the …

WebIndex Terms—Turbo codes, cyclic redundancy check, ordered statistics decoding, normalized Euclidean distance. I. INTRODUCTION T URBO codes [1] have been adopted in the long-term evolution (LTE) systems due to the fact that they can not only achieve high throughput with their parallel decoding architecture, but also support almost any code ... Webdecoding using different biased LLR values was proposed in [14] to refine the error performance of low-order OSD algorithms. This decoding approach performs …
WebFeb 13, 2024 · We now show that the decoder framework involves no penalty in performance in terms of metrics mean-squared-error (MSE) or bit error rate (BER). That is, the decoder can be designed to achieve any one of them. Importantly, it addresses the overfitting problem that was described in Sec. I. Theorem 1. WebThe ordered-statistics decoding (OSD), as a universal decoder for block codes, rekindled the interests recently [12]–[18]. For a linear block code C(n,k) with minimum distance d H, an OSD with the order of m = ⌈d H/4−1⌉ is asymptotically optimum approaching the same performance as
