    A SIC and ML approach for MIMO non-orthogonal multiple access signal detection by Arun Kumar, Nishant Gaur, Aziz Nanthaamornphong

    Published 2025-02-01
    “…One of the top candidates for an enhanced radio architecture is Optical Non-Orthogonal Multiple Access (O-NOMA), which is based on Multiple inputs and Multiple Outputs (MIMO). The identification of signals at the receiver terminal is more difficult due to the employment of a lot of antennas. …”

    Joint beamforming for multiuser SCFDE block transmission system in frequency selective MIMO channels by Li-zhou Xu, Jian JIANG, Sheng DING, Ying-guan WANG

    Published 2013-03-01
    “…Single carrier frequency domain equalization (SCFDE) joint beamforming in frequency selective multiple input multiple output (MIMO) channels under the multi-user scenario was analyzed.Firstly,the frequency domain beamforming was transformed to a time domain filtering beamforming.By using the time domain model,the signal to interference plus noise(SINR)expression of every receiver at the decision point was shown after the frequency domain minimum mean square error(MMSE)equalization.Under a given quality of service(QoS)constraint of every receiver,the optimal beamforming coefficients minimizing the total transmitted power from all transmitters were found through solving a convex semidefinite programming (SDP) problem relaxed from a nonconvex quadratically constrained quadratic programming(QCQP)problem.Simulation demonstrates that the total transmitted power from all transmitters varies regularly with different settings deployed by the model.…”

    The PARAFAC-MUSIC Algorithm for DOA Estimation with Doppler Frequency in a MIMO Radar System by Nan Wang, Wenguang Wang, Fan Zhang, Yunneng Yuan

    Published 2014-01-01
    “…The PARAFAC-MUSIC algorithm is proposed to estimate the direction-of-arrival (DOA) of the targets with Doppler frequency in a monostatic MIMO radar system in this paper. To estimate the Doppler frequency, the PARAFAC (parallel factor) algorithm is firstly utilized in the proposed algorithm, and after the compensation of Doppler frequency, MUSIC (multiple signal classification) algorithm is applied to estimate the DOA. …”
