The Z p Z p 2-additive codes are subgroups of Z p α 1× Z p 2 α 2, and can be seen as linear
codes over Z p when α 2= 0, Z p 2-additive codes when α 1= 0, or Z 2 Z 4-additive codes …

The Z p Z p 2-additive codes are subgroups of Z p α 1× Z p 2 α 2, and can be seen as linear
codes over Z p when α 2= 0, Z p 2-additive codes when α 1= 0, or Z 2 Z 4-additive codes …

The $\mathbb {Z} _2\mathbb {Z} _4\mathbb {Z} _8 $-additive codes are subgroups of
$\mathbb {Z} _2^{\alpha_1}\times\mathbb {Z} _4^{\alpha_2}\times\mathbb {Z} _8^{\alpha_3} …

The Z_pZ_p^2-additive codes are subgroups of Z_p^α_1*Z_p^2^α_2. A Z_pZ_p^2-linear
generalized Hadamard (GH) code is a GH code over Z_p which is the Gray map image of a …

The ℤ 2 ℤ 4 ℤ 8-additive codes are subgroups of Z_2^α_1*Z_4^α_2*Z_8^α_3. A ℤ 2 ℤ 4 ℤ
8-linear Hadamard code is a Hadamard code which is the Gray map image of a ℤ 2 ℤ 4 ℤ 8 …

This PhD thesis is focused on generalized Hadamard (GH) codes obtained from additive
codes over Z_ {p^ s} and some mixed alphabets. GH codes are (n, pn, n (p-1)/p) codes …

The $\mathbb {Z} _p\mathbb {Z} _ {p^ 2}\dots\mathbb {Z} _ {p^ s} $-additive codes are
subgroups of $\mathbb {Z} _p^{\alpha_1}\times\mathbb {Z} _ {p^ 2}^{\alpha_2}\times\cdots …

Aquesta tesi doctoral es centra en els codis Hadamard generalitzats (GH) obtinguts a partir
de codis additius sobre Zps i alguns alfabets mixtes. Els codis GH són codis (n, pn, n (p …
