1. An integrated circuit, comprising:

  • an input node to receive a set of data symbols;

    a partitioner coupled to the input node, wherein the partitioner is to divide the set of data symbols into M irregular subgroups of data symbols, wherein a given irregular subgroup of data symbols in the M irregular subgroups of data symbols includes non-consecutive data symbols in the set of data symbols, and wherein the given irregular subgroup of data symbols includes at least two pairs of adjacent data symbols having different inter-data-symbol spacings in the set of data symbols;

    M modulators coupled to the partitioner, wherein the given irregular subgroup of data symbols is coupled to a given modulator in the M modulators; and

    M output nodes, wherein the given modulator is coupled to a given output node in the M output nodes, and wherein the given output node is to couple to an antenna element in M antenna elements.
