Abstract
In the 3.5 GHz Citizens Broadband Radio Service, 100 MHz of spectrum will be shared between commercial users and federal incumbents. Dynamic use of the band relies on a network of sensors dedicated to detecting the presence of federal incumbent signals and triggering protection mechanisms when necessary. This paper uses field-measured waveforms of incumbent signals in and adjacent to the band to evaluate the performance of a class of matched-filter detectors for these sensors. We find that the proposed detectors exceed the requirements for performance in the presence of co-channel interference from commercial LTE signals, meaning that more commercial devices can use the band in the proximity of sensors. Furthermore, the detectors are robust to out-of-band emissions into this band from adjacent-band radars, which prior studies have found can be significant.Conference Dates
