LYM-type inequalities for tEC/AUED codes
Z. Zhang, X.-G. Xia · IEEE Transactions on Information Theory · 1993
Some LYM-type inequalities are introduced to obtain a relationship between the parameters of t-error correcting/all unidirectional error-detecting codes of length n. As an application of these inequalities, new lower bounds on the redundancies of systematic tEC/AUED codes are derived and an extensive table is given.>
