Abstract

Enveloping techniques using incoherent wavefront multiplexing (WF muxing or K-muxing) will enhance privacy protection on data communications. The disclosure relates to methods and architectures of packing or enveloping data using WF muxing, or K-muxing, for information transport via multiple communication links such as concurrently via multiple satellites, airborne platforms, wireless terrestrial links, and/or other wireless links. The multi-link communications may include the use of cloud transport of multiple WF-muxed data packages. It is focused to appearance of a digital envelop and reliability of enclosed data. The K-muxing on information digital streams before modulation in a transmitter shall provide enhanced data privacy and better availability. The WF multiplexed (WF muxed or K-muxed) information data streams will be individually and concurrently sent to the multiple links accordingly for data transport. The corresponding WF demuxing or K-demuxing will be performed on received K-muxed information digital stream after demodulation in a receiver. The terms of information data or digital information streams are used to differentiate them from those of data signals or digital signal streams. In a transmission, information data usually will be modulated by modulators and converted into data signals before being transmitted. Similarly in a receiver, a received digital signal stream is demodulated by a demodulator and become a digital information stream. The incoherent K-muxing and K-demuxing will be used for processing information data or digital information streams for the benefits of enhanced privacy and better availability. On the other hand, the coherent K-muxing and K-demuxing for processing data signals or digital signal streams will be used for power combining and/or dynamic resource allocations for communications channels.
