Ordered statistics decoding
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 WebJan 9, 2024 · Ordered statistics decoding (OSD) was proposed in 1995 as an approximate maximum likelihood (ML) decoder for block codes [ 7]. OSD has recently aroused interests again because its potential to be a universal decoding algorithm for all short block-length codes. For a linear block code (N,K) with minimum distance dmin, it is proven that an OSD ...
