Spectrum sensing using distributed sequential detection via noisy reporting MAC
This paper considers cooperative spectrum sensing algorithms for Cognitive Radios which focus on reducing the number of samples to make a reliable detection. We develop an energy efficient detector with low detection delay using decentralized sequential hypothesis testing. Our algorithm at the Cognitive Radios employs an asynchronous transmission scheme which takes into account the noise at the...
متن کاملSpectrum Sensing in Cognitive Radios using Distributed Sequential Detection
Cognitive Radios are emerging communication systems which efficiently utilise the unused licensed radio spectrum called spectral holes. They run Spectrum sensing algorithms to identify these spectral holes. These holes need to be identified at very low SNR (≤ −20 dB) under multipath fading, unknown channel gains and noise power. Cooperative spectrum sensing which exploits spatial diversity has ...
متن کاملA Cooperative MAC with Efficient Spectrum Sensing Algorithm for Distributed Opportunistic Spectrum Networks
The spectrum scarcity has led to rethink in the current frequency spectrum usage and develop a new concept of wireless networking. Opportunistic Spectrum Networks (OSNs) have been considered as a promising solution to the problem of spectrum shortage. In this paper, in order to compensate for the need of complex hardware, a novel and efficient Medium Access Control (MAC) framework that integrat...
متن کاملCooperative Spectrum Sensing by Sequential Change Detection in Cognitive Radio
This paper proposes the solution for Spectrum Sensing Problems in Cognitive Radio Networks. For this an Adaptive CUSUM based Test for signal Change Detection algorithm is used. The algorithm is based on sequential change detection techniques which is particularly effective when the parameters are not available apriori or when the correct parameter configuration and the pdf of the signal under t...
