Distributed spectrum sensing in the presence of selfish users

Ali H. Sayed

We study the problem of decentralized spectrum sensing in the presence of selfish secondary users. We employ diffusion strategies to guide the estimation process and a reputation mechanism to encourage secondary users to participate in the sharing of infor ...

Fast algorithm for blind optimization of optical systems. Statistics and methodology

Maria-Alexandra Paun

Adaptive Optics (AO) improves the efficiency of the optical devices in confocal imaging systems by reducing wavefront aberrations. Aberration is caused by imperfections within the system and reduces the optical signal to noise ratio of the resultant images ...

Decentralized Resource Assignment in Cognitive Networks Based on Swarming Mechanisms Over Random Graphs

Ali H. Sayed

This paper proposes a distributed resource assignment strategy for cognitive networks mimicking a swarm foraging mechanism, assuming that the communication among the cognitive nodes is impaired by random link failures and quantization noise. Using results ...

A comparison of in vivo (13) C MR brain glycogen quantification at 9.4 and 14.1 T

Rolf Gruetter, Yves Pilloud, Ruud van Heeswijk

The high molecular weight and low concentration of brain glycogen render its noninvasive quantification challenging. Therefore, the precision increase of the quantification by localized (13) C MR at 9.4 to 14.1 T was investigated. Signal-to-noise ratio inc ...

Ergodic Interference Alignment

Michael Christoph Gastpar

This paper develops a new communication strategy, ergodic interference alignment, for the K-user interference channel with time-varying fading. At any particular time, each receiver will see a superposition of the transmitted signals plus noise. The standa ...

Cooperative Sensing via Sequential Detection

Ali H. Sayed

Efficient and reliable spectrum sensing plays a critical role in cognitive radio networks. This paper presents a cooperative sequential detection scheme to reduce the average sensing time that is required to reach a detection decision. In the scheme, each ...
