After an analysis of the latter, we track the benefits of modified received vectors (that is low Hamming weight and regular structure) through the interpolation step of the GSA and show how the involved homogeneous linear system of equations can be compressed. We show that this compression as well as the recovery of the interpolated bivariate polynomial is particularly simple when the periodicity projection was applied. %@ 978-1-4799-3972-5
