The design of future multi-standard systems is very challenging. Flexible architectures exploiting processing commonalities of the different set of standards cohabiting in the device offer promising solutions. This paper presents a graphical approach for the optimization of multi-standard Software Defined Radio (SDR) systems. The potential of our approach for optimizing multi-standard SDR syste...

Future of wireless communication system designed to merge a variety of services such as voice, data, image and video. These services have various demands on the bandwidth and data rate. So studies has been done to access these requirements, Software Define Radio ( SDR) is being presented as technique offers the possible revolutions the way radios are manufacturing dissemination and used SDR pro...

Software-Defined Radios (SDR) have developed exponentially in recent years. This is due to the high versatility that SDR platforms bring to communications systems. This survey aims at designing, developing, and validating a SDR-based Cognitive Radio Sensing System with a very high functionality to cost ratio. A Radio Band Power Measurement System will be implemented, as a proof of concept, whic...

BACKGROUND China has undergone a rapid demographic and epidemiological transition with fast ecomonic development since the 1980s. Oral health is becoming a major public health problem as the prevalence of non-communicable diseases has greatly increased. Periodontal disease (PD) and caries are among the most prevalent oral diseases. PD accounts for the majority of tooth loss and increases with a...

This paper describes an automatic switching of modulation method to reconfigure transceivers of Software Defined Radio (SDR) based wireless communication system. The programmable architecture of Software Radio promotes a flexible implementation of modulation methods. This flexibility also translates into adaptively, which is used here to optimize the throughput of a wireless network, operating ...

Model-driven design (MDD) is considered a very promising approach to cope with complex software applications such as software defined radio (SDR). This paper proposes a MDD approach for SDR applications. Our approach comprises: (1) DiplodocusDF, a domain-specific modelling language for telecommunication applications, which is based on UML. (2) The mechanism to transform DiplodocusDF models into...

Software defined radio (SDR) technology implements some of the functional modules of a radio system in software enabling highly flexible handsets. SDR devices may be reconfigured dynamically via the download of new software modules. Malicious or malfunctioning downloaded software present serious security risks to SDR devices and networks in which they operate. In this paper, we analyze threats ...

A new kernel dimension reduction (KDR) method based on the gradient space of canonical functions is proposed for sufficient dimension reduction (SDR). Similar to existing KDR methods, this new method achieves SDR for arbitrary distributions, but with more flexibility and improved computational efficiency. The choice of loss function in cross-validation is discussed, and a two-stage screening pr...
