Summary:A system, method, and computer-readable medium for detection and avoidance of victim services in ultra-wideband systems is provided. A detect and avoid module may calculate power averages of OFDM tones. The power of tones may then be measured and compared with power averages of corresponding tones. If a measured tone power exceeds an average power of a corresponding tone by a dynamic threshold, the tone may be identified as associated with an interferer. The threshold may be inversely related to the gain level of an automatic gain control module. The ultra-wideband subsystem may be configured with known bands of victim services of other RF systems, and a tone identified as associated with an interferer that is within a known victim service band may be identified as a victim service. The UWB subsystem may attenuate or otherwise suppress transmission within the victim service band to avoid interfering with the victim service.
