<para>A standard encoder class. This method is discussed in many textbooks; one is: Turbo Coding for Satellite and Wireless Communications by Soleymani, Gao, and Vilaipornsawai. Given a generator matrix in systematic form, <formula id="45">$\mathbf{G}=\left[\mathbf{I}_{k}|\mathbf{P}\right]$</formula>, where <formula id="46">$\mathbf{I}_{k}$</formula> is the identity matrix and <formula id="47">$\mathbf{P}$</formula> is the parity submatrix, the information word <formula id="48">$\bar{s}$</formula> is encoded into a codeword <formula id="43">$\overline{x}$</formula> via: <formula id="49">\[\overline{x}=\mathbf{G}^{T}\bar{s}\]</formula> </para>
