  5. 4. IEEE 802.11n MIMO Modeling and Channel Estimation Implementation

    University essay from Institutionen för systemteknik; Tekniska högskolan

    Author : Xin Xu; [2012]
    Keywords : Simulink; MIMO; OFDM; STBC; Beamforming; MMSE detector; channel estimation;

    Abstract : With the increasing demand of higher data rate for telecommunication, the IEEE802.11n standard was constituted in 2009. Themost important character of the standard is MIMO-OFDM, which not only improves the throughput but also the spectrumefficiency and channel capacity. This report focuses on the physical layer IEEE802. READ MORE

  6. 5. 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
