Digital FMCW for ultrawideband spectrum sensing [PDF]
Radio Science, 2016 AbstractAn ultrawideband digital frequency‐modulated continuous wave sensing engine is proposed as an alternative technique for cognitive radio applications. A dual‐band demonstrator capable of sensing 750 MHz bandwidth in 204.8 µs is presented. Its performance is illustrated from both bench tests and from real‐time measurements of the GSM 900 band and
