摘要： The present disclosure is directed to a system and method for providing directional spectral awareness via an antenna system which includes a single parasitic antenna and a processor, the processor being communicatively coupled with the parasitic antenna. The antenna system allows for quick scanning of all sectors included in a plurality of sectors of an RF environment being monitored by the antenna system. The antenna system also allows for monitoring sectors of interest. The directionality of the parasitic antenna of the antenna system may reduce interference and multipath along with providing improved SNR due to antenna gain, thereby allowing for collection of signals of interest in a more favorable environment, thereby enabling analysis such as frequency and spatial use, signal detection, signal identification, and source geolocation to succeed when it may have failed if an omni-directional antenna were used.

摘要： A spread spectrum communication system includes a transceiver configured to transmit a spread spectrum waveform. The spread spectrum waveform comprises transmitted signals at varying frequencies within a radio frequency spectrum of operation. The frequency variation is controlled according to a hopping sequence. A spectral sensor of the communication system is configured to dynamically scan the radio frequency spectrum of operation and to generate channel occupancy data based upon the scans. A real time hopping sequence generator is configured to dynamically generate the hopping sequence in real time as a function of the channel occupancy data.

摘要： A method, a device, and a system for reconfiguring communication transmission characteristics in response to a changing communication environment is provided. An environment at a communication device is characterized to determine if a transmission parameter associated with processing of a communication signal at a physical layer or a network interface layer should change based on current conditions at the communication device. If a need is identified, a second transmission parameter is selected based on the environment monitoring. A request identifying the second transmission parameter is sent to a manager device using an existing communication link. A response from the manager device is received indicating acceptance or rejection of use of the second transmission parameter in communicating with a second communication device. If the response indicates acceptance of use of the second transmission parameter, the physical layer and/or the network interface layer are reconfigured based on the selected second transmission parameter.

摘要： An apparatus and method for signal separation and SINR improvement is disclosed. In particular, disclosed is an iterative technique whereby a noisy signal, that may include signals from one or more distinct emitters, is first improved through an SINR improvement technique. Next, one signal from the noisy signal is identified and a reference signal substantially free of noise and interference is generated for this signal, and then this reference signal is subtracted from the noisy signal. This process is repeated until no other signals may be identified. In this way, the signal with the highest SINR may be identified first and then removed from the original signal. As such, the identified signal is no longer present as interference for the remaining signals, thus improving each of the remaining signals' respective SINRs.

摘要： The present invention is a method and system for estimating interference. Packet characteristics of relevant packets within the channel at a given point in time may be processed. For example, a power level, occupied frequency and corresponding time references may be accumulated and stored for each relevant packet within the channel at a given point in time. As each packet is processed for demodulation, the channel samples, at which interference occurred, may be appropriately weighted based on the packet characteristics. Advantageously, the nature of the interfering channel traffic may be measured to properly de-weight the interference in a computationally efficient manner.
