摘要： 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.

摘要： Four independent technologies are incorporated in this invention to efficiently and cost effectively implement dynamic last mile connectivity. The four technologies are passive optical networks (PON), Small cell, wavefront multiplexing (or K-muxing), and digital beam forming (DBF). We have filed US patents for communications architectures featuring K-muxing overlaid over low cost of PON. Those inventions relate particularly to resource allocation in passive optical networks (PON) via wavefront multiplexing (WF-muxing or K-muxing) and wavefront demultiplexing (WF-demuxing or K-demuxing). The “WF-muxing in PON” can be configured for performing remote digital beam forming (RDBF) over a service area covered by multiple small cells. The RDBF may generate multiple shaped beams with enhanced connectivity and better isolations over a same frequency slot concurrently to serve multiple users over the coverage area.

摘要： Data files with digital envelops are used (1) for embedded identifiers for digital right management (DRM), and (2) as means delivering additional data or new information via repeated re-broadcasting process by many broadcasting service providers. The new DRM applications offer additional privacy and survivability while data is in storage and/or transported on cloud. Wavefront multiplexing/demultiplexing process (WF muxing/demuxing) embodying an architecture that utilizes multi-dimensional waveforms has found applications in data storage and transport on cloud. Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets that have been “customized processed” and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. A customized set of WF muxing on multiple digital files as inputs including at least a data message file and a selected digital envelop file, is configured to guarantee at least one of the multiple outputs comprising a weighted sum of all inputs with an appearance to human natural sensors substantially identical to the appearance of the selected digital envelop in a same image, video or audio format. The output file is the file with enveloped or embedded messages. The embedded message may be reconstituted by a corresponding WF demuxing processor at destination with the known a priori information of the original digital envelope. In short, digital enveloping/de-enveloping can be implemented via WF muxing and demuxing formulations. WF muxed data featured enhanced privacy and redundancy in data transport and storage on cloud. On the other hand, data enveloping is in a different application domain from most of WF muxing applications as far as redundancy is concerned. Enveloped data is intended only for limited receivers who has access to associated digital enveloped data files with enhanced privacy for no or minimized redundancy.

摘要： Presented is a multi-channel data process to utilize wavefront multiplexing for data storage and data stream transport with redundancy on cloud or in a distribution network. This processing features additional applications for multi-media recording and data communications via transponding platforms including satellites, unmanned air vehicles (UAVs), or others for better survivability and faster accessing. Multiple concurrent data streams are pre-processed by a wavefront multiplexer into multiple sub-channels or wavefront components, where signals from respective data streams are replicated into sub-channels. These replicated data streams are linked via a unique complex weighting vector (amplitude and phase or their equivalents), or “wave-front”, which are also linked by various spatially independent wavefronts. Additionally, probing data streams are embedded and linked via some of the independent wavefronts. Aggregated data streams in sub-channels are unique linear combinations of all input data streams. Generating redundancy for stored or transported data are options in the WF muxing process. Post-processing via a wavefront de-multiplexer converts various sub-channel data streams back to the original data streams, utilizing the embedded known priori data streams as additional knowledge for reducing degrees of freedom to restore orthogonality or independency among multiple wavefronts.
