    This paper presents a three ray propagation model for PCS and μ-cellular services. The salient concept of the proposed model is to maintain cell radii within the Fresnel zone break point. In this region, the path loss slope is similar to free space loss, irrespective of the propagation medium. This analogy is then used to predict cell radii for indoor and outdoor deployment of PCS; requiring vi... View full abstract»

  • Secure communication between tactical and strategic networks

    Publication Year: 1995, Page(s):931 - 935 vol.3
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (228 KB)

    The STU-III program has been very successful in providing secure, high quality communications. The STU-III program, however, has so far been restricted to strategic networks. Tactical networks use devices such as SINCGARS, VINSON, and MINTERM (tactical terminal) which can not interoperate with the STU-III network. The paper discusses the modifications to MINTERM that provide it with a STU-III-comp... View full abstract»

  • Superresolution in the presence of nonuniform noise power

    Publication Year: 1995, Page(s):1209 - 1213 vol.3
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (320 KB)

    The effects of nonuniform noise power in the antenna elements on the performance of the standard MUSIC, reduced MUSIC, and the recursive suppression algorithms are examined. It is shown that the speeds of resolution of all the algorithms are slowed, but their steady-state errors do not exhibit much sensitivity to the noise-power variations. The reduced MUSIC algorithm is shown to provide nearly th... View full abstract»

    The constant modulus (CM) array is an adaptive beamformer that blindly recovers a cochannel source without requiring array calibration. An adaptive signal canceller removes the captured source from the array input, after which the remaining cochannel signals can be processed by a series of similar CM array stages. This multistage cascade CM array may experience a loss in performance when the sourc... View full abstract»

    It has shown that adaptive interference suppression methods for the demodulation of CDMA signals provide immunity to the near-far problem, and perform much better than the conventional matched filter receiver even with perfect power control. Demodulation must, however, be preceded by acquisition of the timing of the desired signal, and conventional methods for acquisition are interference-limited ... View full abstract»

    We present the results of a study of routing algorithms for traffic restoration after a failure in a virtual circuit packet switched wide area network. Standard routing algorithms based on minimizing the steady state network delay may not be appropriate for rerouting the calls after a failure, in view of the transient congestion. We propose alternative routing schemes to reduce the congestion. The... View full abstract»
