Centralized Integrated Spectrum Sensing for Cognitive Radios

Spectrum sensing is the challenge for cognitive radio design and implementation, which allows the secondary user to access the primary bands without interference with primary users. Cognitive radios should decide on the best spectrum band to meet the Quality of service requirements over all available spectrum bands. This paper investigates the integrated centralized spectrum sensing techniques ...

Comments on "Multiple Antenna Spectrum Sensing in Cognitive Radios"

We point out an error in a derivation in the recent paper [1], and provide a correct and much shorter calculation of the result in question. In passing, we also connect the results in [1] to the literature on array signal processing and on principal component analysis, and show that the signal detection methods proposed in [1] follow as special cases of standard results in these fields.
