Remembering that the operator space -here taken to be real and of finite dimension -has Hilbert space structure when equipped with the Hilbert-Schmidt inner product, we can interpret the operators as vectors in this space. The POVM can then be seen as a generalization

1Sub-Nyquist Sampling for Power Spectrum Sensing in Cognitive Radios: A Unified Approach

by Deborah Cohen, Student Ieee, Yonina C. Eldar, Fellow Ieee
"... Abstract—In light of the ever-increasing demand for new spectral bands and the underutilization of those already allocated, the concept of Cognitive Radio (CR) has emerged. Opportunistic users could exploit temporarily vacant bands after detecting the absence of activity of their owners. One of the ..."

of the crucial tasks in the CR cycle is therefore spectrum sensing and detection which has to be precise and efficient. Yet, CRs typically deal with wideband signals whose Nyquist rates are very high. In this paper, we propose to reconstruct the power spectrum of such signals from sub-Nyquist samples, rather
