  • Adaptive Goertzel's Algorithm for DFT Computation with Higher Accuracy 

    Levicky, D.; Drutarovsky, M.; Galajda, P.; Kocur, D.; Marchevsky, S. (Společnost pro radioelektronické inženýrství, 1996-04)
    In this paper the adaptive Goertzel's algorithm applied for required DFT coefficient computation in the harmonic analyser is described. This algorithm utilizes effective combination of the synchronous DFT and window method. ...
  • BAMUD Features Demonstration by System View 

    Longauer, L.; Marchevsky, S.; Kocur, D. (Společnost pro radioelektronické inženýrství, 2004-09)
    Direct-sequence code-division multiple access (DS-CDMA) is a frequently used wireless technology in DS-CDMA communications. The conventional DS-CDMA detector follows a single-user detection strategy in which each user is ...
