摘要:
Radio resource management (RRM) systems and methods are disclosed. In one embodiment, an RRM system comprises: at least one radio frequency unit that transmits and receives signals over an antenna; at least one software defined radio unit configured to communicate with the radio frequency unit, wherein the software defined radio unit generates and receives signals corresponding to different communication systems; at least one processing device coupled to the software defined radio unit; and at least one memory device coupled to the processing device and configured to store instructions which, when executed by the processing device, cause the processing device to: receive a plurality of situational data inputs; select at least one communication system using the situational data inputs; and configure the radio frequency unit and the software defined radio unit to transmit and receive signals using the selected communication system, wherein the configuration is based on the situation data inputs.

摘要:
A system and method for detecting and evaluating structural defects are provided. Baseline data representative of sensed ultrasonic waves that were transmitting into a structure with no defects are stored. Ultrasonic waves are transmitted into the structure from a plurality of actuators that are coupled to the structure. The ultrasonic waves that are transmitted into the structure from the plurality of actuators are sensed, with a plurality of sensors that are coupled to the structure and spaced apart from the actuators, to thereby generate and supply sensor data. Signal difference coefficients are calculated from the baseline data and the sensor data. The calculated signal difference coefficients are spatially mapped to detect one or more structural defects in the structure.
