    • Performance analysis of VSAT networks 

      Hayes, David Paul (Virginia Tech, 1987-03-15)

      Very small aperture terminal (VSAT) networks offer a solution to the increasing demand for low-density voice and data communications. Spread Spectrum and single-channel-per-carrier (SCPC) transmission techniques work ...

    • Performance of a wideband CDMA system under multipath fading 

      Noon, David P., Jr. (Virginia Tech, 1987-03-30)

      The objective of this thesis is to determine the average probability of bit error of an asynchronous, noncoherent, direct-sequence, code-division multiple-access (CDMA) system using wideband M-ary FSK as bandpass ...

    • Signal reconstruction from discrete-time Wigner distribution 

      Cheng, Siuling (Virginia Tech, 1985-03-18)

      Wigner distribution is considered to be one of the most powerful tools for time-frequency analysis of rumvstationary signals. Wigner distribution is a bilinear signal transformation which provides two dimensional ...

    • Spread spectrum satellite multiple access and overlay service 

      Maggenti, Mark A. (Virginia Tech, 1987-03-06)

      This thesis presents two applications of spread spectrum technology to very small aperture terminal (VSAT) satellite communication networks. It describes two spread spectrum multiple access systems which use a form ...
