Abstract: A quiet zone generation technique for acoustic/audio signals is proposed for mitigation of selected noise or interferences over limited areas in free space by injecting the very acoustic noise, interference, or audio feedback signals via iterative processing, generating quiet zones dynamically. This creates undesired noise-free quiet zones. Optimization loops operating iteratively to electronically process cancellation signals consist of three interconnected functional blocks: (1) an acoustic injection array, consisting of pick-up arrays to obtain the interference signals, beam forming networks for element weighting and/or re-positioning, and array elements for noise injections, (2) a diagnostic network with strategically located probes, and (3) an optimization processor with cost minimization algorithms to calculate element weights for updating.

Abstract: A quiet zone generation technique is proposed for interference mitigation for a receive antenna by injecting the very interference signals via iterative processing, generating quiet zones dynamically for receive (RCV) antennas. The receive antenna may feature multiple receiving apertures distributed over a finite area. Optimization loops consist of four cascaded functional blocks; (1) a pick-up array to obtain the interference signals, (2) element weighting and/or repositioning processors, (3) an auxiliary transmit (XMIT) array with optimized element positions, (4) a diagnostic network with strategically located probes, and (5) an optimization processor with cost minimization algorithms. To minimize interferences between transmit (Tx) and receiving (Rx) apertures in limited space of an antenna farm for communications and/or radar applications are very tough problems. However, solutions for co-site interference mitigation may not be generic ones but more specific to geometries of antenna farms, Tx apertures and Rx antenna locations, and beam positions of the Tx beams.

Abstract: This invention aims to present a smart and dynamic power amplifier module that features both power combining and power sharing capabilities. The proposed flexible power amplifier (PA) module consists of a pre-processor, N PAs, and a post-processor. The pre-processor is an M-to-N wavefront (WF) multiplexer (muxer), while the post processor is a N-to-M WF de-multiplexer (demuxer), where N≧M≧2. Multiple independent signals can be concurrently amplified by a proposed multi-channel PA module with a fixed total power output, while individual signal channel outputs feature different power intensities with no signal couplings among the individual signals. In addition to basic configurations, some modules can be configured to feature both functions of parallel power amplifiers and also as M-to-M switches. Other programmable features include configurations of power combining and power redistribution functions with a prescribed amplitude and phase distributions, as well as high power PA with a linearizer.

Abstract: An advanced digital beam forming technique is achieved that is capable of simultaneously forming multiple beams and attenuating the cross-pol component at multiple locations. The proposed invention, comprising a series of signal inputs, optimization loops and weighting processes, successfully eliminates the side effect of an increase of the cross-pol in the process of beam-forming, thus reducing potential interference. This technique utilizes the orthogonally polarized signal component which is already available and can minimize both the horizontally polarized and vertically polarized cross-pol at the same time. The complexity of computation can be reduced by using only part of the orthogonal polarized components in the optimization.

Abstract: A communication system includes a transmitter segment at a source location inputting a plurality of input signals to be transmitted. The input signals are transformed to wavefront multiplexed signals (WFM signals), and the WFM signals are modulated into WFM waveforms. The WFM waveforms are transmitted through a segment of propagation to a receiver segment; wherein the segment of propagation includes a plurality of UAV based transmission channels among the WFM waveforms; wherein the WFM waveforms are transmitted over the transmission channels; wherein the receiver segment receives the WFM waveforms from the transmission channels. Demodulation is performed on the received WFM waveforms to convert the received WFM waveforms to received WFM signals individually. A wavefront de-multiplexing transform is performed on the received WFM signals to recover individual desired signals.

Abstract: The present invention features novel methods of implementing configurable arrays for personal portable devices including hand-held mobile devices and re-locatable wireless devices, utilizing a wireless communications system that employs multiple individual hubs and/or base-stations. The digital beam forming (DBF) methodology utilizes multiple low gain elements conformal to the mechanical contours of handheld devices to function as arrays. The distributed N element arrays dynamically provide the options of reconfigurable shaped beams with near hemispheric radiation patterns for various handheld orientations and conditions by various users, while also supporting operations of multiple orthogonal beams concurrently connecting to multiple hubs. The larger the N becomes, the more flexibility the residing devices can provide.

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.
