A computer-implemented method, a system, and a computer program product include program code that obtains, from a controller, temporal objectives and configuration specifications. The program code adjusts weighting for multiple concurrent modes. The program code optimizes each mode of the multiple concurrent modes. The program code discovers conflicts exist between the optimized multiple concurrent modes and resolves the conflicts. The program code allocates resources to the optimized multiple concurrent modes.

Balanced resource allocator for heterogeneous multi-objective systems

A computer-implemented method, a computer program product, and a system include a processor(s) that produces a set of beamforming vectors, each vector produced based on a distinct set of parameters. To produce vector of the vectors, the processor(s) obtains, from receive antennas, data comprising a waveform comprising slots with boundaries, from a first collection window. The processor(s) determines the parameters (e.g., silent portion length and signal portion length) and determines which slots of the waveform contain signal operating instructions. The processor(s) aligns the slot boundaries, utilizing the data, based on determining which slots of the waveform contain signal operating instructions. The processor(s) extracts the signal portion and the silent portion, determines a covariance for each, and determines a vector and eigenvalue. From the set, the processor(s) selects a vector and applies the vector to a second collection window to suppress interference in data received within the second collection window.

Multiple input multiple output radio interference suppression and range extension

There is set forth herein, in one embodiment, obtaining with a radiofrequency receiver a combined radiofrequency signal having a first stream combined with a second stream, wherein the first stream has a first power level, and wherein the second stream has a second power level, the first power level of the first stream being greater than the second power level of the second stream, wherein the radiofrequency receiver includes one or more antenna; processing the combined radiofrequency signal to recover a first digital bitstream associated to the first stream; and recovering a digital bitstream associated to the second stream using the first digital bitstream.

Power multiplexed radiofrequency signal processing

Embodiments of the present invention include a system, method and computer program product for mitigating interference in data received by a multiple antenna array. Processor(s) executing program code identify signals from users, including active users, and by identifying these signals, mitigate interference and jamming in the received data, overall.

Multi-antenna jamming/interference protection for waveforms

Provided are processes for suppressing jamming signals that may include use of a signal processing circuit. A signal processing circuit can be configured to obtain a jamming signal and a feedback signal, process the jamming signal and the feedback signal to determine a cancellation signal for use in suppressing the jamming signal, and output the cancellation signal to a radio-frequency transmitter. The signal processing circuit may be further configured to obtain a transmission signal, determine a jamming channel from the jamming signal and a feedback channel from the feedback signal, and combine the transmission channel, jamming channel, and feedback channel to determine a transfer function, where the transfer function is configured to determine the cancellation signal.
