FR3-DUALIS: from signal processing to spectrum allocation for real-time wideband full-duplex ISAC—a prototype validation at FR3

open access: yesnpj Wireless Technology
Integrated sensing and communication (ISAC) has emerged as a key enabling technology for future 6G networks. Existing implementations encounter fundamental trade-offs: single-band full-duplex systems require complex self-interference cancellation (SIC ...

Wideband Spectrum Sensing technique based on Goodness-of-Fit testing

open access: yes, 2015
Recently, Goodness-of-Fit (GoF) based spectrum sensing has been proposed as a method for blind narrowband spectrum sensing. GoF based spectrum sensing has the nice feature that, compared to Energy Detection, it needs fewer samples to achieve the same ...

Emerging Technologies and Access to Spectrum Resources: the Case of Short-Range Systems [PDF]

open access: yes
Traditional regulatory arrangements have constrained access to radio frequency spectrum. This has resulted in artificial scarcity of spectrum. The paper addresses the issue of whether technological developments in short-range systems (e.g.

Spectrum monitor for cognitive radio

open access: yes, 2010
The concept of a cognitive radio assumes that the receiver is able to determine the activity level across a large range of spectrum in order to assign a channel for its use.

Non-compressive wideband spectrum sensing with sub-Nyquist sampling rates

open access: yes, 2013
In this paper, we propose a low complexity and reliable wideband spectrum sensing technique that operates at sub-Nyquist sampling rates. Unlike the majority of other sub-Nyquist spectrum sensing algorithms that rely on the Compressive Sensing (CS ...

Comparative Study of Wideband Speech Spectral Quantization Schemes

open access: yes, 2000
In this treatise a range of Line Spectrum Frequency (LSF) Vector Quantization (VQ) schemes were studied comparatively, which were designed for wideband speech codecs. Both predictive arrangements and memoryless schemes were investigated.

Compressed correlation-matching for spectrum sensing in sparse wideband regimes

open access: yes
In this paper, we consider a novel compressed correlation-matching (CCM) approach for spectrum sensing of wideband sparse signals. We derive a general closed-form estimate of the wideband sparse signal level from compressed observations, while providing ...
