Abstract

Polar codes were recently proposed by Arikan and are constructed based upon a phenomenon that called channel polarization. The basic polarization matrix is given as . A challenging problem related to the design of polar codes is choose a suitable generator matrix , where is an arbitrary integar and , since in this state we have several choices for , unlike Arikan works that has only just one linear form. In this paper, we have compared status , that is simplest case from changing matrix with Arikan's work. As carry out simulations for this schema to show that there is eventuality selection unsuitable channel for the transmission information and find the best generator matrix. Finally have been proposed a briefly on the probability of error and complexity in this schema.
