WebRECOVERABLE CODES OF DISTANCE 5 AND 6 VIA BINARY CONSTANT WEIGHT CODES LINGFEI JIN Abstract. It was shown in [7] that the length n of a q-ary linear locally recoverable code with distance d> 5 is upper bounded by O(dq3). Thus, it is a challenging problem to construct q-ary locally recoverable codes with distance d> 5 and length …

WebThis chapter is concerned with the existence and constructions of binary perfect constant-weight codes. These codes are related to the Johnson scheme. It is conjectured that … WebLet A(n,d,w) denote the maximum possible number of codewords in an (n,d,w) constant-weight binary code. We improve upon the best known upper bounds on A(n,d,w) in numerous instances for n/spl les/24 and d/spl les/12, which is the parameter range of existing tables. Most improvements occur for d=8, 10, where we reduce the upper … how many weeks are in 2021
