Estimating the direction of arrival (DOA) sources is an important problem in aerospace and vehicular communication, localization, radar. In this article, we consider a challenging multisource DOA estimation task, where receiving antenna array composed noncoherent subarrays, i.e., subarrays that observe different unknown phase shifts at every snapshot (e.g., due to waiving demanding synchronizat...

The performances of almost all available fault tree analysis tools are limited by the performance of the prime implicant computation procedure they use. All these procedures manipulate the prime implicants of the fault trees explicitly, so that their complexities are directly related to the number of prime implicants to be generated. This paper presents a new analysis method of coherent as well...

We consider several single antenna transmitters communicating with a multi-antenna receiver, with the latter decoding transmitted information at the end of each symbol time. Motivated by the optimal noncoherent detector in a Rayleigh fading channel, we propose a noncoherent energy-based communication scheme that does not require any knowledge of instantaneous channel state information at either...

Abstract— The connectivity and capacity of large ad hoc networks have been studied extensively under standard point-to-point physical layer assumptions. However, extensive recent research has demonstrated the improvement in performance possible when multiple radios concurrently transmit in the same radio channel. In this paper, we consider how such physical layer cooperation improves the connec...
