Abstract: System and methods are disclosed for collecting detailed list of frequencies along with any relevant information such as users, time of day, weather, ionospheric conditions, quality of the transmission. This information is used to create a detailed frequency map. The frequency map is continuously updated. The frequency map is used to generate an optimum list of frequency bands that can be used for frequency sharing. Having a real-time frequency map allows for fast and reliable switching between optimum frequencies if a primary user is detected during transmission.

Abstract: System and methods enabling radio communications that are operating in noisy environments using OFDM (Orthogonal Frequency Division Multiplexing) are disclosed. A spread OFDM transmitter that generates OFDM symbols that may include multiple copies of IFFT symbols is disclosed. A spread OFDM receiver is disclosed for receiving the spread OFDM symbols. Other methods for symbol detection, frequency offset correction, and equalization are disclosed.

Abstract: Establishment of a Terrain Independent Communication using—The HF band (3-30 MHz) and VHF (30 to 300 MHz) frequency spectrums that is provided for use as shared spectrum by the FCC. Different segments within the spectrum are in use today by emergency and utility companies in an intermittent fashion. The utilization of the shared spectrum as of date is very low (typically below 20%). The invention seeks to identify optimum, and less frequented frequency ranges within the spectrum to establish terrain independent connectivity between base stations and end points up to 1200-mile radius. This connection is used to provide terrain independent communication for data communication for point to point and point to multi-point applications. Typically, this connection is used for short bust automatic data acquisition applications, such as sensor monitoring, and other communication applications.
Abstract: System and method for automatic communication with remote devices enabling remote control and monitoring of the devices. The primary target is for low-power, remote devices running narrow or relatively narrow bandwidths, though the method is not restricted for any payload limits. The system enables two devices on a fully automated basis to identify each other, sound the radio paths between them to discover spectrum characteristics, select and exchange a vector of currently unused and optimum frequency bands for communication. Once defined, the devices use the frequency bands for automatic communication. The method enables devices to configure themselves for exchange of data and then the transfer of data. The base station and/or end points have the ability to initiate a connection and data transfer and use software defined radios to implement this capability.
