A lattice prediction device (200) for predicting a number of lattice points falling inside a bounded region in a given vector space. The bounded region is defined by a radius value, 5 a lattice point representing a digital signal in a lattice constructed over the vector space. The lattice is defined by a lattice generator matrix comprising components. The lattice prediction device (200) comprises a computation unit (201) configured to determine a predicted number of lattice points by applying a machine learning algorithm to input data derived from the radius value and the components of lattice generator matrix.
