  1. 1. Block Diagonalization Based Beamforming

    University essay from KTH/Teknisk informationsvetenskap

    Author : Darshan Patil; [2017]
    Keywords : ;

    Abstract : With increasing mobile penetration multi-user multi-antenna wireless communication systems are needed. This is to ensure higher per-user data rates along with higher system capacities by exploiting the excess degree of freedom due to additional antennas at the receiver with spatial multiplexing.

  3. 2. Filter Bank Multi-Carrier Modulation

    University essay from KTH/Kommunikationsteori

    Author : Frédéric De Poret; [2015]
    Keywords : ;

    Abstract : During the last years, multi-carrier modulations have raised a particular interest due to their high spectral efficiency and the possible assumption of flat frequency fading. The most broadly used multi-carrier modulation is the CP-OFDM. READ MORE

  4. 3. Study of Channel Estimation in MIMO-OFDM for Software Defined Radio

    University essay from Institutionen för systemteknik

    Author : Qi Wang; [2007]
    Keywords : SDR; MIMO-OFDM; Channel Estimation; Computational Complexity;

    Abstract : The aim of the thesis is to find out the most suitable channel estimation algorithms for the existing MIMO-OFDM SDR platform. Starting with the analysis of several prevalent channel estimation algorithms, MSE performance are compared under different scenarios. READ MORE

  5. 4. A study of closed loop space time block coding techniques for MIMO-OFDM

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Shabbar Ali Khan; [2006]
    Keywords : closed loop space time block coding;

    Abstract : In this dissertation, the STBC-OFDM technique is therefore investigated in order to improve the bit error rate performance of such wireless communication systems speci¯cally those using multiple transmitter and receiver antennas.An investigation is undertaken of STBC with two transmit and one receive antennas as proposed by Alamouti together with quasi-orthogonal STBC with four transmit and one receive antennas.

  6. 5. Intercell Interference Management in an OFDM-based Downlink

    University essay from Institutionen för systemteknik

    Author : Jessica Heyman; [2006]
    Keywords : intercell; interference; OFDM; 3GPP Long Term Evolution; 3GPP LTE; frequency domain scheduling; power allocation; cell edge users;

    Abstract : Efficient radio resource management is of paramount importance for achieving the high bit rates targeted by the 3GPP for the 3GPP Long-Term Evolution. The radio air interface must be able to provide both high peak bit rates and acceptable cell-edge bit rates. READ MORE
