We present two iterative algorithms to interpolate graph signals from only a partial set of samples. Our methods are derived from classical iterative schemes in presence of irregular samples and compared with existing graph signal reconstruction algorithms in order to study the rate of convergence and the computational efficiency. The experimental results demonstrate the effectiveness of the proposed methods.
