A radio-on-dense-wavelength-division-multiplexing (DWDM) transport system based on injection-locked Fabry-Perot laser diodes (FP LDs) with four microwave carriers and large effective area fiber (LEAF) transmission was proposed and demonstrated. Good performance of bit error rate (BER) and intermodulation distortion to carrier ratio (IMD/C) over a-50 km of LEAF was obtained. Signal quality meets...

Does radio programming by Studio Tamani in Mali create an empowering environment for women’s voices? Contributing to existing theoretical discussions on and empowerment, this article examines the need discuss empowerment not from perspective of women as individuals, but “webs relations”, thus allowing intersubjectivity evolving relationships with others be considered. “Webs relations” refers br...

 Frequency modulation (FM) is a form of radio broadcasting which is widely used nowadays and has been in use for over a century, since 1906 when the first radio audio broadcast was made.  FM performance is severely degraded when the system noise amount exceeds a critical level, above which the traditional FM receiver breaks.  Traditional methods used in radio receivers divide the problem int...

Young people can be valuable motivational resources for health promotion. A project implemented from 2009 through 2013 in a small American Indian community in northwest Arizona recruited American Indian young people aged 10 to 21 as agents of change for health promotion through radio programming. Thirty-seven participants were recruited and trained in broadcasting and creative writing technique...

This project aims at investigating key issues in radio interface design for practical frequency-selective fading channels. It is focused on the new opportunities and challenges that arise when considering broadband radio systems, with an emphasis on packet data transmission. The purpose of such a radio interface is to carry packets to or from wireless users. The destination of packets may be on...

This paper presents a speech/music discriminator for radio recordings, based on a new and computationally efficient region growing technique, that bears its origins in the field of image segmentation. The proposed scheme operates on a single feature, a variant of the spectral entropy, which is extracted from the audio recording by means of a short-term processing technique. The proposed method ...

In this paper, direction of arrival (DOA) algorithms for Frequency Modulated (FM) point source have been implemented over a real time system. The source was a commercial FM radio station broadcasting at 89 MHz. Experiments were carried out in order to determine the location of a FM transmitter using spectral and subspace algorithms. The complete Radio Frequency (RF) front end and Uniform Linear...

The paper presents an analysis of scientific and practical development software-configurable radio monitoring module based on RTL2832U tuner in Simulink environment order to scan a given ultra-short-wave (VHF) frequency range perform automatic search, counting output the number broadcasting stations. Given is structural circuit diagram modernized SDR-receiver (Software Defined Radio) with inclu...
