Phase transformation of repeated signals

摘要

Devices, systems, methods, and other embodiments associated with phase based transformation of repeated signals are described. In one embodiment, an apparatus includes duplication logic configured to duplicate a string of data to form a duplicate string of data. Transformation logic is configured to modify phases associated with the string of data to generate a modified string of data. Signal generation logic is configured to generate a signal for wireless transmission where the signal having at least the modified string of data and the duplicate string of data.

1. An apparatus, comprising:
combining logic configured to map multiple bits of different strings of data to multiple symbols of a constellation diagram, wherein the multiple symbols are mapped to the different strings of data and constellation points of the constellation diagram are not located at 45 degrees with respect to a real axis and an imaginary axis of the constellation diagram; duplication logic configured to duplicate the string of data symbols to form a duplicate string of data symbols; transformation logic configured to modify phases associated with at least some data symbol values of the string of data symbols by modifying the at least some data symbol values to corresponding conjugate values, to rotate some other symbols in the string of data symbols to non-conjugate values, and to generate a modified string of data symbols based on the modified at least some data symbol values and the rotated data symbol values; and signal generation logic implemented in at least hardware configured to generate a signal for wireless transmission, the signal having at least the modified string of data symbols and the duplicate string of data symbols.
