1. A device for generating a signal, comprising:
a memory;
at least one processor coupled to the memory and configured to:
obtain a sequence of input samples;
obtain a first set of sequences, wherein the first set of sequences is based on discrete prolate spheroidal sequences associated with eigenvalues having a value larger than a first threshold;
determine a first projected sample sequence comprising a projection of the sequence of input samples to the first set of sequences; and
generate the signal based on the first projected sample sequence.
