  3. 2. 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.
