Justesen's construction--The low-rate case (Corresp.)
Edward J Weldon · IEEE Transactions on Information Theory · 1973
By using the more general class of BCH codes, rather than RS codes as originally proposed, the results of Justesen [1] are improved for code rates below 0.07. The value ofd/nfor the new codes approaches the Varsharmov-Gilbert hound (0.5) as the rate approaches zero.
