Apparatus for orthogonal 16-qpsk modulated transmission

A method comprising:

• activating an apparatus that comprises a plurality of quadrature phase shift key modulators coupled to a phased array of antenna elements configured into pluralities of antenna elements, the pluralities of antenna elements coupled to a Plurality of phase shifters for generating N modes of orthogonal (OAM) radio waves where N is equal to or greater than 2;
• and
• modulating QPSK symbols onto each of the N modes of orthogonal (OAM) radio waves by respective ones of the plurality of QPSK modulators, each of the respective ones of the plurality of QPSK modulators being coupled to a respective one of the pluralities of antenna elements to modulate the QPSK symbols onto a respective one of the N modes of orthogonal (OAM) radio waves,
• wherein each of the N modes of orthogonal (OAM) radio waves operates as an independent data channel, and
• wherein the apparatus is configured to transmit the modulated orthogonal (OAM) radio waves, each on a respective one of the pluralities of antenna elements.

One or more computer-readable hardware storage device having stored therein a set of instructions which, when executed by one or more processors of a computer, causes the computer to execute operations comprising:

• generating an independent data channel on each of N modes of orthogonal (OAM) radio waves by:
• activating an apparatus that comprises a plurality of quadrature phase shift key QPSK modulators coupled to a phased array of antenna elements configured into pluralities of antenna elements, each of the pluralities of antenna elements coupled to a plurality of phase shifters for generating N modes of orthogonal (OAM) radio waves where N is equal to or greater than 2;
• and
• modulating QPSK symbols onto each of the N modes of orthogonal (OAM) radio waves by respective ones of the plurality of QPSK modulators, each of the respective ones of the plurality of QPSK modulators being coupled to a respective one of the pluralities of antenna elements to modulate the QPSK symbols onto a respective one of the N modes of orthogonal (OAM) radio waves,
• wherein each of the N modes of orthogonal (OAM) radio waves operates as an independent data channel, and
