  1. 6. 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

  3. 7. Precoding in MIMO, OFDM to reduce PAPR (Peak to Average Power Ratio)

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Muhammad Irfan Ishaq; Yasir Ali Khan; Muhammad Talha Gul; [2012]
    Keywords : Peak to Average Power Ratio;

    Abstract : One of the critical issues of systems utilizing Orthogonal Frequency Division Multiplexing (OFDM) is the high peak to the average power ratio of OFDM signals. We have used Precoding as a way to mitigate the PAPR problem. Furthermore the performance of Precoded OFDM in fading multi-path channels has been studied. READ MORE

  4. 8. Implementation of MIMO-OFDM System for WiMAX

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Muhammad Atif Gulzar; Rashid Nawaz; Devendra Thapa; [2011]
    Keywords : MIMO; OFDM; WiMAX;

    Abstract : Error free transmission is one of the main aims in wireless communications. With the increase in multimedia applications, large amount of data is being transmitted over wireless communications. This requires error free transmission more than ever and to achieve error free transmission multiple antennas can be implemented on both stations i.e. READ MORE
