An energy detection-based active spectrum sensing scheme is proposed to carry out spectrum sensing and secondary transmissions simultaneously. It successfully avoids the widely used quiet periods, which have at least two shortcomings. First, periodic

As the precondition of dynamic spectrum access, spectrum sensing (SS) plays an important role in the spectrum utilization in cognitive wireless mesh networks (WMNs). However, the accuracy and efficiency of SS is always significantly compromised by th

A geo-location assisted real-time in-band spectrum sensing scheme is proposed to carry out the spectrum sensing and secondary transmissions in parallel. It is able to avoid the widely used “quiet periods,” which have at least the following two di

The performance of energy detection-based spectrum sensing is greatly compromised by the problem of noise uncertainty consisting of device noise uncertainty and environmental interference uncertainty. This paper first compares these two kinds of unce
