  • Publication number: 20170308387
    Abstract: An RF digitization and collection system (RFDCS) and methods for implementing the RF digitization and collection system to manage an application storage and retrieval space (App Space), wherein the App Space includes apps that may perform various offline and/or real-time transforms of RF signals received, stored, or played back on the RFDCS. Also, in the various embodiments, the RFDCS may govern the system resources available to these apps while ensuring that the RFDCS's core system functions are not impacted by the execution of one or more of these apps in the App Space. Thus, the RFDCS may enable users to utilize real-time signal processing by running various specialized apps without compromising the RFDCS's core system function, thereby promoting dynamic “on-the-fly” transformation of raw RF signals without compromising the user's overall experience.

  • Patent number: 9621201
    Abstract: Methods and systems for emulating an interference environment include combining a plurality of emulated interfering signals and transmitting the plurality of emulated interfering signals using at least one transmitter. The methods and systems may further include receiving a selection of a frequency region, where the plurality of emulated interference signals are transmitted in all or part of the selected frequency region. The selected frequency region may be at least partially within an Industrial, Scientific and Medical (ISM) radio band. The plurality of emulated interfering signals may be transmitted to at least one device to test the interference immunity of the at least one device.

  • Patent number: 9356642
    Abstract: A radiofrequency transceiver device includes at least one reconfigurable integrated circuit (RIC) and a system controller that is able to reconfigure the at least one RIC to perform specific processing tasks. The specific processing tasks may be related to processing at least one radiofrequency signal that is received by, stored on, retrieved from and/or transmitted by the radiofrequency transceiver device. Embodiments may also include one or more reconfigurable integrated circuit applications (RIC Apps) that may be executed, at least in part, on the at least one RIC.

  • Patent number: 8982971
    Abstract: A multi-carrier signal is typically comprised of many equidistant sub-carriers. This results in periodicity of spectrum within the bandwidth of such a multi-carrier signal. An unknown multi-carrier signal with equidistant sub-carriers can thus be sensed together with its sub-carrier spacing by finding a discernable local maximum in the cepstrum (Fourier transform of the log spectrum) of the multi-carrier signal.

  • Publication number: 20140129556
    Abstract: A system and method for receiving storing, manipulating and distributing RF data. A computing device receives and stores collected RF data. A requesting user issues a request for the RF data file, which request includes one or more modification parameters. The computing device selects one or more processing algorithms based on the one or more modification parameters and applies the selected processing algorithms to the collected RF data. The computing device provides the manipulated RF data to the requesting party in response to the request.
