Abstract
Embodiments of a communication circuit are described. This communication circuit includes an input node (212) to receive a set of data symbols and a partitioner (216) coupled to the input node. The partitioner is to divide the set of data symbols into M irregular subgroups of data symbols, a given one of which includes non-consecutive data symbols in the set of data symbols. Moreover, this 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. This communication circuit also includes M modulators (218-1, 218-N1) coupled to the partitioner, where the given irregular subgroup of data symbols is coupled to a given modulator in the M modulators. Furthermore, the communication circuit includes M output nodes, where a given output node in the M output nodes is coupled to the given modulator and is to couple to an antenna element in M antenna elements (226).
