Abstract: A receiver with orthogonal beam forming technique is achieved that is capable of differentiating different signal components within the received composite signal. An adaptive processor is used to eliminate the signal component whose phase information is known or can be calculated. The phase information of the major component of a signal can be easily acquired by using a limiter. The phase information of other signal components can be acquired by their direction information and other characteristics, such as modulation scheme, etc. Multiple orthogonal beams can be formed by eliminating one unwanted signal component each time by the adaptive processor until all unwanted signal is eliminated. Thus, a composite signal from multiple sources can be broken down into their component signals.

For advanced design, ground diagnostic signals with optimizing processor can be added to guarantee recovery quality.

Abstract: A direct broadcasting satellite (DBS) system features a capability of coherently combining amplified signals powers from various broadcasting transponders without modifying the satellite segment. Organized DBS transponders would function as an equivalent DBS transponder with a higher EIRP. Power allocations are via a mechanism in an uplink transmitter in a ground segment and power combining mechanisms are in user receivers in a user segment. Specifically, the transmitter generates mixtures of input signals by using Wavefront-Multiplexing and transmits wavefront-multiplexed (WFM) signals which are sent concurrently through multiple parallel channels of transponders in the satellite segment. A receiver in the user segment separates the mixtures of received amplified WFM signals and coherently combines amplified components by various transponders by adaptive equalizing and Wavefront De-Multiplexing processors.

Abstract: A system is provided for high speed optical fiber data transmission by generating artificial wavefronts along multiple paths exhibiting spatial mutual orthogonality. Multiple independent signal streams are “structured” over a group of different propagation paths that are coherently organized by wavefront multiplexing and de-multiplexing techniques. Therefore, signal streams with enhanced throughput and reliability may be fully recovered at destinations via embedded diagnostic signals and optimization loops. Multiple optical channels are matched with multiple orthogonal wavefronts created by a signal pre-processor. A receiving end signal post-processor dynamically aligns propagation paths via diagnostic signals and orthogonality of the propagation wavefronts electronically. The multiple optical channels are coherently bonded into a single virtual channel, thereby increasing data bandwidth while reducing interference and unwanted multi-path effects.

Abstract: This invention takes advantages of common coverage areas of two groups of concurrent shaped fan beams in a field-of-view by both clusters of multiple flying UAVs to function as two linear arras on sky as parts of embodiments of this invention. It shows two information data sets of transmitted signals to two groups of users independently are preprocessed by a wavefront multiplexing (WF muxing) transformation before uploaded to the linear arrays on sky. Only users in the common coverage areas can access to both WF Muxed data streams delivered by the two independent arrays in sky and thus are capable to reconstitute the two information data sets.

Abstract: A communication system and method for a deep space spacecraft receiver to perform post-processing to dynamically combine received signal power coherently for pre-processed signal streams radiated non-coherently from a distributed, multiple element, Ka-band transmitting array via multiple concurrent propagation paths. Mutually orthogonal data and pilot signals travel though the multiple propagation paths. A pre-processor utilizing wavefront multiplexing restructures signal streams on the ground into multi-channel wavefrom structures along with injections of pilot signals for diagnostic and probing purposes. These restructured, or “wavefront multiplexed” (WFM) signals are transmitted through propagation channels to a receiver on the spacecraft, wherein adaptive equalization and wavefront de-multiplexing coherently separates the mixtures of received WFM signals.

Abstract: Presented are MIMO communications architectures among terminals with enhanced capability of frequency reuse by strategically placing active scattering platforms at right places. These architectures will not depend on multipaths passively from geometry of propagation channels and relative positions of transmitters and those of receivers. For advanced communications which demand high utility efficiency of frequency spectrum, multipath effects are purposely deployed through inexpensive active scattering objects between transmitters and receivers enable a same frequency slot be utilized many folds such as 10×, 100× or even more. These active scatters are to generate favorable geometries of multiple paths for frequency reuse through MIMO techniques. These scatters may be man-made active repeaters, which can be implemented as small as 5 to 10 watt lightbulbs for indoor mobile communications such as in large indoor shopping malls.

Abstract: A novel terrestrial wireless communications technique for terrestrial portable terminals including hand-held mobile devices and fixed wireless instruments, utilizing a spoke-and-hub communications system, having a plurality of individual hubs and/or base-stations all in communications with the portable terminals. The portable terminals and the hubs are assigned to use incompatible polarity formats in terms of circularly polarity (CP) and linearly polarity (LP). In forward links, a signal processed by the LP ground telecommunications hubs is radiated through multiple antennas with various LP polarities to an individual CP user simultaneously. The multiple paths are organized via assignments of a plurality of polarities, frequency slots, and directions by wavefront multiplexing/demultiplexing techniques such that the same communications assets including frequency spectrum may be re-used by other users. The same polarity diversity methods can be extended to peer-to-peer communications.

Abstract: Presented are methods that utilize wavefront multiplexing for enabling linearly-polarized terminals to access circularly-polarized satellite transponders. The methods disclosed herein feature (1) polarization formation capability that renders transmitted signal conditioned on circularly-polarized channels through multiple linearly-polarized feeds, and (2) polarization-conversion capability that compensate path differentials introduced by electromagnetic wave propagation channels. Data streams to be transmitted are pre-processed by a wavefront multiplexer into multiple wavefront components in linear polarization formats, where signals from respective data streams are replicated into linearly-polarized sub-channels. These replicated data streams are linked via a unique complex weighting vector (amplitude and phase or their equivalents), or “wavefront”, which are also linked by various spatially independent wavefronts.

Abstract: 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.
