    A population of mobile terminals communicating with a central station over a packet-switched multiple-access radio channel is investigated. In land mobile radio communication, in which terminals cannot sense the carrier transmitted from other terminals (either because they are out-of-range or obstructed), a central controlled multiple access system in which a central station broadcasts idle/busy i...

    A simple analytic model of the multipath fading channel is presented. For a given echo density and distance of communication, it is shown that as the system bit-rate is increased, the probability of unacceptable distortion will rapidly increase. As the bit-rate is reduced, flat fading will increase. In between these two cases there exists a bit-rate for which the mnltipath components can be exploi... View full abstract»

    A new digital signaling technique that is particularly suited for channels impaired by multipath fading is presented. The proposed modulation scheme employs a continuous-wave (CW) tone to calibrate the mobile channel against the multipath-induced phase uncertainties. This technique is applicable to quaternary phase shift keying as well as to more complicated signal constellations such as M-ary pha... View full abstract»

  • Frequency offset receiver diversity for differential MSK

    A new receiver diversity scheme for differential detection of minimum shift keying (MSK) is proposed. The signal from each receiving branch is translated to a different IF frequency. The IF signals are summed and then detected by a common differential detector. The diversity scheme does not need phase adjusters, signal quality measurement circuits or a switching controller; moreover the error rate... View full abstract»

    Novel receiver structures are introduced which improve the bit error rate performance of differentially detected MSK and QPSK systems. These new receiver structures are based on 1) combining with feedback, 2) a simple Viterbi decoder which uses one- and two-bit detector outputs for maximum-likelihood sequence estimation, and 3) using the correlation of noise for the partial removal of its effect p...

    A newly developed bent-slot antenna for UHF portable communication equipment is introduced. The bent-slot antenna, modified from a half-wave slot element, is designed to have both vertical and horizontal elements and is intended to achieve the improvement of the receiving performance in the urban area. The antenna system characteristics such as current distribution, radiation pattern, gain, and in... View full abstract»
