A NLLS Based Sub-Nyquist Rate Spectrum Sensing for Wideband Cognitive Radio
M. R. Avendi, K. Haghighi, A. Panahi +1
For systems and devices, such as cognitive radio and networks, that need to be aware of available frequency bands, spectrum sensing has an important role. A major challenge in this…
On Optimum Causal Cognitive Spectrum Reutilization Strategy
Kasra Haghighi, Erik G. Ström, Erik Agrell
In this paper we study opportunistic transmission strategies for cognitive radios (CR) in which causal noisy observation from a primary user(s) (PU) state is available. PU is assum…
A Wideband Spectrum Sensing Method for Cognitive Radio using Sub-Nyquist Sampling
Moslem Rashidi, Kasra Haghighi, Arash Owrang +1
Spectrum sensing is a fundamental component in cognitive radio. A major challenge in this area is the requirement of a high sampling rate in the sensing of a wideband signal. In th…
