Wireless communication of data symbols

A method of receiving data symbols comprising:

• receiving a received symbol corresponding to a constellation point selected from corresponding constellation points of a constellation pattern comprising replications of a first constellation, each replication having a replication offset relative to a neighbouring replication and each replication alternating between corresponding to the first constellation and a constellation of a set of at least one axis mirrored constellation of the first constellation around at least one of the real axis and an imaginary axis;
• folding the received symbol into a region corresponding to the first constellation to generate a decoding symbol;
• and
• determining a received data symbol value from the decoding symbol.

A transmitter for transmitting data symbols, the method comprising:

• a unit for providing a constellation pattern comprising replications of a combined constellation with different translations such that each replication has a combination replication offset relative to a neighbouring replication, the combined constellation comprising at least a first constellation and a second constellation with a first translation offset between the first constellation and the second constellation and the second constellation corresponding to an axis mirroring of the first constellation around at least one of a real axis and an imaginary axis;
• a channel symbol selector for selecting symbols for transmission from the constellation pattern, the selection including for a data value corresponding to a first constellation point of the first constellation selecting a symbol from replications of the first constellation point in the constellation pattern to meet a criterion;
• and
• a transmitter unit for transmitting the selected symbols.

A receiver for receiving data symbols comprising:

• a receiving unit for receiving a received symbol corresponding to a constellation point selected from corresponding constellation points of a constellation pattern comprising replications of a first constellation, each replication having a replication offset relative to a neighbouring replication and each replication alternating between corresponding to the first constellation and a constellation of a set of at least one axis mirrored constellation of the first constellation around at least one of the real axis and an imaginary axis;
• a processor for folding the received symbol into a region corresponding to the first constellation to generate a decoding symbol;
• and
• a decision unit for determining a received data symbol value from the decoding symbol.
