  • Viterbi Decoded Linear Block Codes for Narrowband and Wideband Wireless Communication Over Mobile Fading Channels 
    Staphorst, Leonard (University of Pretoria, 2006-09-29)
    Since the frantic race towards the Shannon bound [1] commenced in the early 1950’s, linear block codes have become integral components of most digital communication systems. Both binary and non-binary linear block codes ...
  • Vowel perception in severe noise 
    Swanepoel, Rikus (University of Pretoria, 2010)
    A model that can accurately predict speech recognition for cochlear implant (CI) listeners is essential for the optimal fitting of cochlear implants. By implementing a CI acoustic model that mimics CI speech processing, ...
