    A packet radio network employing FFH-CDMA as multiple access technique is studied. We focus on the acquisition process and we examine the effect of multiple-access interference. The relationship between the maximum number of tolerable interfering transmissions and the number of frequencies used in frequency hopping is investigated. The bounds to the probability of acquisition as well as approximat... View full abstract»

    The research and development of OFDM/COFDM for digital television broadcasting has received considerable attention and has made a great deal of progress in Europe. OFDM/COFDM has already been implemented in digital audio broadcasting and is being considered for terrestrial digital television and HDTV broadcasting. The advantages of COFDM claimed by the advocates in Europe have also caught the atte... View full abstract»

    Interference from the daytime skywave signal of one broadcasting station to the groundwave signal of a co-channel station located several hundred kilometers away has been observed in certain parts of the world. The need for a better of skywave propagation at daytime, the Radiocommunications Sector of the International Telecommunications Union (ITU-R, formerly known as the International Radio Consu...

    There are two competing transmission systems for downstream digital transmission on hybrid fiber/coax cable networks: quadrature amplitude modulation (QAM), and vestigial sideband modulation (VSB). Both QAM and VSB are bandwidth efficient, and have the same bandwidth efficiency. Detailed calculations and simulations of QAM and VSB transmission on hybrid fiber/coax are reported here. It is shown th... View full abstract»

    This report studied the effects that solar and geomagnetic activity has on ionospheric propagation. The goals of this study were to identify solar emissions that help and hinder high frequency broadcasting and to determine how much the signal strength and, the maximum usable frequency of the one-hop and two-hop F2 mode decreased during disturbed propagating conditions. A series of measurements wer... View full abstract»
