Coordinate Interleaved Power Index Modulation

A method for wireless reception of data, the method comprising the steps of:

• receiving each of one or more component-interleaved symbols on a respective carrier given by a determined carrier index and with a determined power value, wherein
• the data is represented by a group of bits divided into symbol bits and carrier index bits;
• and
• the one or more component-interleaved symbols that correspond to complex symbols are obtained by:
• sequentially forming real and imaginary components of intermediate symbols out of said symbol bits;
• and
• interleaving said real and/or imaginary components among the intermediate symbols;
• wherein the carrier index and the power value being determined for each of the one or more component-interleaved symbols based on the carrier index bits;
• and
• determining the data from the one or more component-interleaved symbols by a predefined detection method.

An apparatus for wireless transmission of data, comprising:

• a circuitry configured to:
• divide a group of bits representing the data into symbol bits and carrier index bits;
• generate one or more component-interleaved symbols that correspond to complex symbols that are obtained by
• sequentially forming real and imaginary components of intermediate symbols out of said symbol bits and
• interleaving said real and/or imaginary components among the intermediate symbols;
• determine a carrier index and a power value for each of the one or more component-interleaved symbols based on the carrier index bits;
• and
• a transceiver configured to transmit each of the one or more component-interleaved symbols on a respective carrier given by the determined carrier index and with the determined power value.
