Spectrum Sensing at the ICC 2010

The International Communications Conference (ICC) was recently hold in Cape Town, South Africa... just before the World Cup Soccer championship kicks off. In the ICC's final program we can find quite a lot of papers related to spectrum sensing. While I do not have access to the proceedings of the conference yet I wrote down a list of the spectrum sensing related papers organized in the sections sensing schemes, coopearitve spectrum sensing, sensing policy, and other papers related to spectrum sensing. Let's go.

Edit: I had access to a copy of the proceedings and I revised some of these papers. If you are interested take a look at the posts related to the ICC 2010. Proceedings available online: IEEE Xplore.

Spectrum Sensing Approach Based on Optimal Stochastic Resonance Technique under Color Noise Background in Cognitive Radio Networks
Di He, Chen He, Lingge Jiang, Yingpei Lin (Shanghai Jiao Tong University, China)
This was the first time I see the term Stochastic Resonance. Googling it I found that Stochastic Resonance refers to a peak that appears in the power spectrum of a dynamical system subject to both periodic forcing and random perturbation. This peak dissapears when either the forcing or the perturbation is absent.

Doubly Sequential Energy Detection for Distributed Dynamic Spectrum Access
Nikhil Kundargi, Ahmed Tewfik (University of Minnesota, USA)

We study the distributed sequential energy detection problem in the context of spectrum sensing for cognitive radio networks. We formulate a novel Doubly Sequential Energy Detector (DSED) and provide a comprehensive study of its performance. Specifically, we present the first method that sequentially combines the decisions of the Cognitive Radio nodes wherein each node is running an independent Sequential Energy Detector (SED). Through extensive simulations it is demonstrated that (i) our novel sequential version of the energy detector delivers a significant throughput improvement of 2 to 6 times over the fixed sample size test while maintaining equivalent operating characteristics as measured by the Probabilities of Detection (P_D) and False Alarm (P_FA), and (ii) the Doubly Sequential Procedure at the Base Station further boosts the SED performance while improving the robustness for shadowed Cognitive Radio nodes. For example, for a P_D > 0.95, our simulations demonstrate that the DSED has a P_FA < 0.20 while utilizing upto 8 times fewer samples than the equivalent energy detector upto a Signal to Noise Ratio of -10 dB, below which its performance gracefully degrades.

Spectrum Sensing policy

An Optimal Algorithm for Wideband Spectrum Sensing in Cognitive Radio Systems.
Pedram Paysarvi Hoseini, Norman C. Beaulieu (University of Alberta, Canada)

An optimal wideband spectrum sensing algorithm which jointly detects the primary activities over multiple narrowband channels is presented. The algorithm enhances the overall secondary user performance while protecting the primary network at a desired level. The problem is formulated as an optimization problem to maximize the available secondary throughput capacity given a bound on the imposed aggregate interference. It is demonstrated that the problem can be solved as a convex optimization if certain practical constraints are applied. Simulation results attest that the proposed algorithm achieves a superior performance compared to contemporary algorithms.

Energy-Efficient Spectrum Sensing for Cognitive Radio Networks
Hang Su, Xi Zhang (Texas A&M University, USA)

This paper focuses on the spectrum sensing issues in the unslotted cognitive radio networks with wireless fading channels. To overcome the energy-inefficiency problem of the existing continuous/fixed-schedule spectrum sensing schemes in the cognitive radio networks, we propose an efficient spectrum sensing scheme for secondary users (SUs). The design goal of our proposed scheme is to save the sensing energy consumption while guaranteeing the priority of the primary users (PUs) and the spectrum opportunity for SUs in terms of available spectrum usage time. In particular, our proposed energy-efficient spectrum sensing scheme adaptively adjusts the spectrum sensing periods and determines between the presence and vacancy of the PU by taking advantage of PU’s activity patterns. We also develop a novel two-threshold based sequential sensing policy to reduce the false alarm probability while limiting the missed detection probability. We conduct simulations to validate and evaluate our proposed scheme.
