1. A method comprising:
identifying input data including at least one of an array size, an antenna element spacing, a phase-shifter resolution, a specified coverage region, or an antenna element pattern;
processing the input data and an initial beam through a non-decreasing concave utility function using a cyclic coordinate descent algorithm to generate a wide beam meeting one or more design specifications; and
producing a codebook including the wide beam.
