Relaying network is expected to play an important role in the future wireless network. This paper presents a scheme of two-hop cellular network with fixed relay nodes (FRN). Based on this scheme, co-channel interference and SIR received by BS and FRN are analyzed. Both the theoretical analysis and simulation results show that the SIR can be improved(More)
Image mining is a nontrivial process to discover valid, novel, potentially useful, and ultimately understandable knowledge from large image sets or image databases. With the rapid development of rough set theory in recent years, more and more people have applied this theory to different research fields. In order to solve the curse of dimensionality in image(More)
Studies have shown that bone marrow-derived cells play an important role in tumor recurrence after chemotherapy and radiotherapy. In this study, we examined the relationship between the accumulation of Gr-1+CD11b+ cells and tumor recurrence after irradiation in tumor-bearing mice. By transplanting bone marrow cells into whole body-irradiated mice depleted(More)
In recent years, there has been an upsurge of interest in relay-augmented infrastructure-based networks. And the radio resource management of relay system has great influence on the system performance. This article presents two frequency reuse schemes based on fixed relay system. Scheme I let the second hop link (between fixed relay node and mobile station)(More)
Ad hoc networks are wireless networks composed of mobile devices with limited power and transmission range. Advance reservations are a useful method to allocate resources of various kinds in many different environments, and especially be useful for wireless ad hoc networks that require network quality of service, which need advance reservation to support(More)
