This paper analyzes the energy detector that is commonly used to detect the presence of
unknown information-bearing signals. The algorithm simply compares the energy (or power) …

The authors address the energy detection performance of a detector, or more specifically,
the determination of the required signal-to-noise ratio (P/sub s//P/sub n/) for given …

By using Shannon's sampling formula, the problem of the detection of a deterministic signal
in white Gaussian noise, by means of an energy-measuring device, reduces to the …

This paper presents another look at the problem of energy detection of unknown signals
over different fading channels. We start with the no diversity case and present some …

In this letter we consider the effect of combined slow and fast fading on the energy detection.
We model the received signal power distribution and propose a simplified approximation to …

This letter proposes an energy detection scheme based on short windows to detect the
presence of a burst signal that spans over a short period of time. For practical use, the …

The focus of this thesis is on the binary signal detection problem, ie, if a signal or signals are
present or not. Depending on the application, the signal to be detected can be either …

Spectrum sensing is a key enabler of cognitive radio but generally suffers from what is called
a signal-to-noise ratio (SNR) wall, ie, a minimum SNR below which it is impossible to …

A novel approach is introduced for the analysis of energy detection of unknown deterministic
signals, where the energy detector uses dual diversity reception. The energy detector is …

In this work we perform an asymptotic analysis of estimated noise power (ENP) energy
detector (ED) to derive the condition for the existence of the SNR wall phenomenon. We …
