   A block code of length \(n\) is quasi-cyclic if, for each codeword \(c_1 \cdots c_{\ell} c_{\ell+1} \cdots c_n\), the string \(c_{n-\ell+1} \cdots c_n c_1 \cdots c_{n-\ell}\), where each entry is cyclically shifted by \(\ell\) increments, is also a codeword.
-  Code for which \(\ell = 1\) are cyclic, while codes for which \(\ell = 2\) are called \cite{double circulant}.
+  Code for which \(\ell = 1\) are cyclic, while codes for which \(\ell = 2\) are called \textit{double circulant}.
 
   The generator of an \([mn_0,mk_0]\) quasi-cyclic linear code is representable as a block matrix of \(m \times m\) circulant matrices \cite{manual:{Thomas A.
