In this paper, a new watermarking method based on spread spectrum technique, which we call capacious spread spectrum (CSS) is proposed. In this method, unlike the traditional spread spectrum watermarking (TSS), more than one pseudo noise (PN) sequence will be deployed. Also, a novel method to produce orthogonal PN-sequences is achieved. Moreover, it is(More)
Vehicle-to-vehicle (V2V) communications have recently received growing attentions due to the fact that it enables dynamic wireless data exchange between nearby vehicles, offering the opportunity for safety improvements and information sharing. In this paper, we investigate the performance analysis of a two-way amplify-and-forward (AF) multi-relay(More)
In this paper, we study a general practical stochastic energy harvesting (EH) model where in, an EH relay is able to harvest energy from the radio frequency (RF) radiation in a super capacitor. The different aspects of this stochastic energy harvesting model (SEHM) are discussed and the performance of a point-to-point (P2P) wireless link is evaluated in the(More)
BACKGROUND There are various clinical symptoms of thalassemia intermedia, and they lie roughly between those of major and minor forms of the disease. Patients with thalassemia intermedia occasionally require blood transfusions. This renders them susceptible to pulmonary arterial hypertension (PAH) syndrome, which is one of the most significant complications(More)
In this paper, we investigate the performance of energy harvesting relay-aided cooperative system wherein, the source node transmits hierarchical signal to the relay and destination nodes. But, since in cooperative networks relays are often nearer to the source than the destination, the relay node is able to decode multi-resolution signal whereas, the(More)
