We introduce a rapid interferer detector that uses compressed sampling (CS) with a
quadrature analog-to-information converter (QAIC). By exploiting bandpass CS, a blind sub …

Cross-correlation is a promising method for highly sensitive spectrum sensing. By computing
the cross-power spectrum from a pair of sensors and performing time averaging, significant …

Congestion of the radio spectrum, caused by licensed primary users and an increasing
demand for new devices, has created a need for alternative methods of radio spectrum use …

This paper presents a low power and highly linear passive spectrum scanner based on the
filtering by aliasing principle. The scanner utilizes a linear periodically time-varying circuit …

Traditionally, radio frequency detection or ambient spectrum sensing has required high-
performance spectrum analyzers and RF signal analyzers, leading to relatively high costs …

<? Pub Dtl=""?> Dynamic spectrum access relying on spectrum sensing requires reliable
detection of signals in negative signal-to-noise ratio (SNR) conditions to prevent harmful …

Radio transceivers capable of dynamic spectrum access require frequency-agile
transmitters with a clean output spectrum. High-Q filters are difficult to implement on chip and …
