  • Iipponen, Päivi (1996-10-16)
    This master's Thesis studies the problem of detecting double-talk in hands-free mobile telephony. Double-talk, i.e. simultaneous speech of the two parties of a telephone conversation, causes major problems to acoustic echo ...
  • Kupiainen, Teemu (1998-06-03)
    By using multirate signal processing, the signal may be shifted in the frequency domain to lower frequencies. In this work, a new algorithm based on a simple filter bank is developed. The sampling rate is reduced and the ...
  • Huupponen, Antti (2003-03-12)
    Mobile devices are becoming more widely spread, and they are used for various applications. When these applications are becoming more and more like normal desktop applications, one must address the question of security. ...
  • Laine, Teemu; Paranko, Jari; Suomala, Petri (2010)
    Purpose – The objective of this paper is twofold. First, it aims at defining the concept of the downstream shift in the context of the machinery manufacturers. The second aim of the paper is to analyze the potentially ...
  • Mickos, Roy (1992)
    DPCM-koodaus (Differential Pulse Code Modulation) on suhteellisen vanha menetelmä informaatiolähteen tietomäärän pienentämiseksi. Menetelmää tukemaan on kehitetty vakiintunut lineaarinen ennusteteoria, jota on menestyksellä ...
  • Uusitalo, Leena (2001-06-06)
    Työn tarkoituksena on selvittää, millaisia muistikomponentteja DRAM-muistit (dynaamiset hajasaantimuistit) ja eDRAM-muistit (sulautetut DRAM-muistit) ovat ja kuinka niitä voidaan hyödyntää erilaisissa sovelluksissa.Työssä ...
  • Kreutzer, Joose; Lehtinen, Pekka; Kallio, Pasi (2010)
    In this paper, we demonstrate and analyze the solubility and distribution of dried europium(III)-chelate dyed nanoparticles in mini channels of milled polystyrene (PS) cartridges. The particular objective for the study is ...
  • Kataja, Jyrki (2000-06-07)
    The aim of this study has been to supervise drilled pile execution and to gather experiences from both the contractor side and the manufacturer side to make this product well-known and accepted by main clients as well. ...
  • Laurent, M. Sechu (1986)
    BY 1976, when the United Nations gave recommendations on the initiation of rural water supply programmes, Tanzania was already implementing he own, launched in 1971. In march 1973, Temporary Standards of Quality of ...
  • Hämäläinen, Laura (2015-04-08)
    Tämän diplomityön tarkoituksena oli kehittää paremmaksi jo olemassa olevaa lääkeluovutussysteemiä, joka perustuu kahden valmistusmenetelmän yhdistelmää käyttäen kehitettyihin, deksametasonia (DEX) sisältäviin, biohajoaviin ...
  • Ashenafi, Kibret (1986)
    Iron is objectionable constituent when present in drinking and process water more than the desired limit. Different iron removal methods and their modifications have been applied for iron removal. However, conventional ...
  • Heikkinen, Jari (2001-06-06)
    Työssä verrataan MOVE-arkkitehtuurin suorituskykyä kaupalliseen Texas Instrumentsin TMS320C62x DSP-prosessoriin. Testisovelluksina käytettiin nopeaa Fourier-muunnosta ja diskreettiä kosinimuunnosta. MOVE-arkkitehtuurissa ...
  • Kiayani, Adnan Qamar (2009-11-04)
    The recent interest in I/Q signal processing based transceivers has resulted in a new domain of research in flexible, low-power, and low-cost radio architectures. The main advantage of complex or I/Q up- and downconversion ...
  • Savinainen, Jari (1997-12-10)
    Development of a modern GSM mobile phone requires a lot of research work as well as new innovative ideas. Before these ideas can be put into practice in a form of new state of the art mobile equipment, the phone has to ...
  • Himanen, Teemu (1997-05-14)
    The world-wide success of the GSM standard together with concepts like mobile office and multimedia set demands for the data transmission capability of GSM. The user data rate of 9.6 kbit/s is no longer sufficient for ...
