Multi-antenna transmitter for multi-tone signaling

A system, comprising:

• a first device, wherein the first device includes:
• 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 antenna elements, wherein the given modulator is coupled to a given antenna element in the M antenna elements, and wherein the given antenna element is to transmit signals corresponding to the given irregular subgroup of data symbols;
• and
• a second device, wherein the second device is to receive signals from the first device via a wireless communication channel, and wherein the second device is to demodulate the received signals and is to detect the set of data symbols.

A method for communicating data, comprising:

• partitioning a 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;
• modulating the M irregular subgroups of data symbols using M modulators, wherein the given irregular subgroup of data symbols is modulated using a given modulator in the M modulators;
• and
• transmitting signals using M antenna elements, wherein a given antenna element in the M antenna elements transmits signals from the given modulator.

A transmitter, comprising:

• a memory;
• a communication circuit coupled to the memory, 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.
