  1. 1. Robust MIMO Precoding on Real-World Measured Channels

    University essay from KTH/Signalbehandling

    Author : Filip Hedenskog; [2015]
    Keywords : MIMO; maximin; imperfect CSIT; real-world measured channels; uncertainty set; worst-case robustness;

    Abstract : It is well known that multi-input multi-output (MIMO) wireless communication systemsthat employ precoding techniques are capable of meeting the high expectations of modernand future wireless communication standards. In order to fully utilize these techniques, thecommunication system typically requires information of the channel, commonly referred toas channel state information (CSI). READ MORE

  3. 2. Performance Analysis of OSTBC with Hybrid Decode-Amplify and Forward relay network

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Kanoksak Wannatrong; Mohammed Abul Hayat; [2013]
    Keywords : Cooperative communication; symbol error rate; moment generating function; orthogonal space-time block code. ;

    Abstract : In the last few decades, the innovation of Wireless communication has been developed very fast in order to improve the performance of communication systems. Especially,a concept of Multiple Input and Multiple Output (MIMO) is purposed to fulfill a high data rate service such as high quality video conference. READ MORE

  4. 3. Performance Analysis of Decode and Forward Relaying with Keyhole in Nakagami-m Fading Channels

    University essay from Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Author : pawan khadka; [2012]
    Keywords : decode and forward; orthogonal space time block codes; Nakagami-m fading; keyhole effects; symbol error rate; moment generating function; fading severity parameter;

    Abstract : Fading has always been a major obstacle in the effective transmission of signals from the transmit antenna to the receive antenna. The innovation of multiple-input multiple-output (MIMO) system has led to the regression of the adverse effect of these fading entities and thus provided a higher data rate communication while maintaining the quality of service (QoS).

  5. 4. 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

  6. 5. Analysis of OSTBC in Cooperative Cognitive Radio Networks using 2-hop DF Relaying Protocol

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Muhammad Mustafa Tahseen; MatiUllah Khan; Farhan Ullah; [2011]
    Keywords : Cognitive Radio; Cooperative Communication; Alamouti STBC; OSTBC; Rayleigh Fading; Energy Detector; DF Relay; Maximum Likelihood; MRC;

    Abstract : To achieve cooperative diversity in cognitive radio network, Decode and Forward (DF) protocol is implemented at Cognitive Radios (CRs) using Orthogonal Space Time Block Coding (OSTBC). The 2-hop communication between source and destination is completed with the help of Cognitive Relays (CRs) using Multiple Input Multiple Output (MIMO) technology within the network. READ MORE
