  4. 18. APPLYING DISTRIBUTED ORTHOGONAL SPACE TIME BLOCK CODING IN COOPERATIVE COMMUNICATION NETWORKS

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : James Adu Ansere; Odion Ehimiaghe; [2012]
    Keywords : Decode and Forward; BER; DOSTBC; Cooperative communications;

    Abstract : In this research, we investigate cooperative spectrum sensing using distributed orthogonal space time block coding (DOSTBC). Multiple antennas are introduced at the transmitter and the receiver to achieve higher cooperative diversity in the cooperative wireless (CW) networks. READ MORE

  5. 19. Reliable, Low-delay Communication in Wireless Sensor Networks

    University essay from KTH/Reglerteknik

    Author : Mahesh Bogadi Shankar Prasad; [2011]
    Keywords : ;

    Abstract : Wireless sensor networks consist of tiny computers embedded into an environment which can monitor almost anything - such as light, motion, proximity, temperature, biometrics and chemical substances. Actuators conjoined to sensor networks can be used not only to sense the environment, but also to interact with it. READ MORE

  6. 20. Stereo coding for the ITU-T G.719 codec

    University essay from Signaler och System

    Author : Tomas Jansson; [2011]
    Keywords : stereo coding; ITU-T G.719; audio; stereo models; stereokodning; ITU-T G.719; ljud; stereomodeller;

    Abstract : This thesis presents a stereo coding architecture for the ITU-T G.719 fullband mono codec. G.719 is suitable for teleconferencing applications with a competitive audio quality for speech and audio signals that are encoded at 32, 48 and 64 kbps. READ MORE
