CM-LSTM Based Spectrum Sensing. [PDF]
Sensors (Basel), 2022 This paper presents spectrum sensing as a classification problem, and uses a spectrum-sensing algorithm based on a signal covariance matrix and long short-term memory network (CM-LSTM). We jointly exploited the spatial cross-correlation of multiple signals received by the antenna array and the temporal autocorrelation of single signals; we used the ...

Sensing Opportunities in UMTS spectrum [PDF]
2007 2nd International Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2007 The UMTS radio frequency spectrum is a highly expensive commodity. While the UMTS standards make very efficient use of the allocated bands there is however opportunity for further advancements. This paper focuses on opportunistic use of the UMTS spectrum as a means of ensuring that the maximum possible use of this valuable resource is made.
