In this paper, we present the implementation of a system that identifies modulation complex radio signals. This is realized using an artificial intelligence model developed, trained, and integrated with Microsoft Azure cloud. We consider cloud-based platforms offer enough flexibility processing power to use them instead conventional computers for signal based on intelligence. tested software-de...

The magnetic alloy loaded radio-frequency system has been installed in the KEK 12 GeV synchrotron. This system is a high field gradient radio-frequency system and is designed to operate not only as a fundamental harmonic system to increase the insufficient matching voltage, supplied by 4 conventional ferrite cavities but also as a second radiofrequency system to alleviate the space charge effec...

in this paper, we consider a cooperative cognitive radio network in which there is an ofdm primary link and multiple single carrier secondary links.the primary link is required to maintain its secrecy rate above a predefined threshold. if the secrecy rate requirement is not satisfied, the secondary system help primary link to maintain its secrecy rate requirement. in doing so, the secondary trans...

In this article we review the fundamental issues involving the simulation of the radio channel and discuss some of the more challenging simulation topics that are pertinent to the radio channel. Radio and propagation channels The propagation channel, together with the transmit and receive antennas, constitute the radio channel. Figure 1 depicts the propagation and radio channel's place in a rad...

Using request radio shows as a base interactive model, we present the Steerable Optimizing Self-Organized Radio (SoSoRadio) system as a prototypical music recommender system with robust automatic playlist generation. This work describes a web-based radio system that interacts with current listeners through the selection of periodic request songs from a pool of nominees.

A lot of hardware components are used to make a conventional radio communication system, the complexity of these hardware can be reduced with help of Software Defined Radio (SDR) which is a form of wireless communication. Software Defined Radio implemented system allows us to make alteration in it or operate it with help of a software, thus making the system flexible and reconfigurable. The sys...
