LPWS Algorithm for Wideband Spectrum Sensing

Wireless Personal Communications, 2016
Wideband or multi-band spectrum sensing is an essential functionality for cognitive radio (CR) networks. It enables a secondary user to identify spectral holes dynamically and transmit opportunistically so as not to interfere with cohabiting primary users over the same bands.

A new approach for spectrum sensing in wideband

Eurocon 2013, 2013
A new algorithm of the spectrum sensing is proposed in this paper. The spectrum sensing methods presented in this paper are optimised to implement these in FPGA based embedded systems. The low power and highly parallelised architecture of FPGA requires low complexity in implementation of separate processing units - spectrum sensors (SpS).

Wideband spectrum sensing by compressed measurements

2012 IEEE Symposium on Computers and Communications (ISCC), 2012
In this paper we introduce a new method for wideband spectrum sensing which uses the received signal compressed measurements to determine the occupancy status of each subchannel. In the cognitive radio systems, wideband spectrum sensing in high utilization regimes increases the speed of the access to the spectrum holes.
