  • Reduzierung des Spitzen-zu-Durchschnitts-Leistungsverhältnisses in OFDM-Systemen
    Anusha Chacko / Grace John M.
    Orthogonal Frequency Division Multiplexing (OFDM) ist eine vielversprechende Technologie in der drahtlosen Kommunikation. Ein hohes Spitzen-zu-Durchschnitts-Leistungsverhältnis (PAPR) ist eines der Herausforderungen von OFDM-Systemen. Ein hoher PAPR zwingt den Hochleistungsverstärker (HPA) dazu, in seinem linearen Bereich mit großem Dynamikbereich zu arbeiten, wo die Energieeff...

  • Réduction du rapport puissance crête/puissance moyenne dans les systèmes OFDM
    Anusha Chacko / Grace John M.
    Le multiplexage par répartition orthogonale de la fréquence (OFDM) est une technologie prometteuse dans le domaine des communications sans fil. Le rapport puissance crête/puissance moyenne (PAPR) élevé est l’un des défis majeurs des systèmes OFDM. Un PAPR élevé oblige l’amplificateur de puissance élevée (HPA) à fonctionner dans sa zone linéaire avec une large gamme dynamique, o...

  • Riduzione del rapporto potenza di picco/potenza media nei sistemi OFDM
    Anusha Chacko / Grace John M.
    Il multiplexing a divisione di frequenza ortogonale (OFDM) è una tecnologia promettente nel campo delle comunicazioni wireless. L’elevato rapporto potenza di picco/potenza media (PAPR) è una delle sfide più impegnative dei sistemi OFDM. Un PAPR elevato costringe l’amplificatore di potenza elevata (HPA) a funzionare nella sua regione lineare con un ampio intervallo dinamico, dov...

  • Redukcja stosunku mocy szczytowej do średniej w systemach OFDM
    Anusha Chacko / Grace John M.
    Ortogonalna multipleksacja częstotliwości (OFDM) jest obiecującą technologią w komunikacji bezprzewodowej. Wysoki stosunek mocy szczytowej do średniej (PAPR) jest jednym z trudnych wyzwań systemów OFDM. Wysoki współczynnik PAPR zmusza wzmacniacz mocy (HPA) do pracy w zakresie liniowym o szerokim zakresie dynamicznym, gdzie wydajność energetyczna jest bardzo niska. Niniejsza ksi...

  • Redução da relação potência de pico/média em sistemas OFDM
    Anusha Chacko / Grace John M.
    A multiplexação por divisão ortogonal de frequência (OFDM) é uma tecnologia promissora na comunicação sem fios. A elevada relação potência de pico/média (PAPR) é um dos desafios dos sistemas OFDM. Um PAPR elevado obriga o amplificador de alta potência (HPA) a operar na sua região linear com ampla faixa dinâmica, onde a eficiência energética é muito baixa. Este livro apresenta u...

  • Speaker Recognition using MFCC and Vector Quantization
    Chacko Anusha / John M. Grace
    Speaker Recognition is one of the most useful biometric recognition techniques in this world where insecurity is a major concern. This book introduces a method for speaker recognition on the basis of the individual information included in speech waves. This can mainly be divided into two parts speaker identification and speaker verification. Speaker Identification find outs whi...

  • Fluidization
    John M. Matsen / John R. Grace
    Fluidized beds have gained prominence in many process in­ dustries (including chemicals, petroleum, metallurgy, food and pharmaceuticals) as a means of bringing particulate solids into contact with gases and/or liquids. Many fluidized bed operations are physical in nature (e.g. drying, coating, classification, granulation, and rapid heat transfer as i...
