Srivastava code

In coding theory, Srivastava codes, formulated by Professor J. N. Srivastava, form a class of parameterised error-correcting codes which are a special case of alternant codes.

Definition

The original Srivastava code over GF of length n is defined by a parity check matrix H of alternant form
where the α_i and z_i are elements of GF

Properties

The parameters of this code are length n, dimension ≥ n − ms and minimum distance ≥ s + 1.
