We describe the clinical patterns and case-fatality rate associated with severe Rift Valley fever (RVF) in patients who were admitted to the Gizan regional referral hospital during an outbreak of RVF in Saudi Arabia from September through November 2000. A total of 165 consecutive patients (136 men and 29 women) were prospectively studied; all were(More)
In this paper we study the feasibility of IEEE 802.11ah radio technology for internet of things (loT) and machine to machine (M2M) use cases. Devices in internet of things and machine to machine networks are foreseen to communicate wirelessly. Therefore, it is of foremost importance to have a reliable, low-energy wireless technology available that may be(More)
In this paper, we present an enhanced least mean square (LMS) based feedback loop interference canceller algorithm intended to be used in digital terrestrial broadcasting single frequency network (SFN) via single on-channel repeater system (OCR). The feedback loop interference is caused by the coupling that could exist between transmitting and receiving(More)
This work presents a new technique for blind and joint estimation of symbol timing and carrier frequency offset in wireless orthogonal frequency division multiplexing (OFDM) systems. The joint estimation is achieved by sensing the interference introduced at the fast Fourier transform (FFT) output when a carrier frequency or timing offsets exist. The(More)
