    Approaches to improve performance of 60 GHz radio-0verFiber fronthaul links
    Lim, C ; Tian, Y ; Nirmalathas, A ; Lee, KL (OSA Publishing, 2020)
    In this paper, we review the work we have done to improve the performance of users located at the cell boundary of a 60 GHz radio-over-fibre fronthaul using coordinated-multipoint (CoMP) together with non-orthogonal-multiple-access (NOMA).

    Multi-Level Code NOMA for Radio-over-Fiber based Fronthaul Links
    Lim, C ; Tao, Y ; Nirmalathas, A (IEEE, 2020)
    The inherent centralized control architecture of radio-over-fiber (RoF) enables advanced coordination functionality to be implemented in a RoF-based mobile fronthaul to facility network management and coordination. This advanced coordination functionality enhances the performance of disadvantaged end users located further away from the remote radio head (RRH) or at the cell edges. In this paper, we review our work incorporating multi-level code based non-orthogonal multiple access (NOMA) to improve the performance of users located further away from the RRH with poor channel gain.

    Indoor Optical Wireless Communications using Few-mode Based Uniform Beam Shaping and LMS Based Adaptive Equalization
    Li, J ; Lim, C ; Nirmalathas, A (IEEE, 2020-09-01)
    An indoor optical wireless communication system employing few-mode based uniform beam shaping and adaptive LMS equalization is demonstrated. Results show that superior uniformity is obtained and LMS equalization with step size of 0.01 and tap length of 45 achieves the best performance.

    Demonstration of High-speed Indoor Optical Wireless Communications using Few-mode Based Uniform Beam Shaping
    Li, J ; Lim, C ; Nirmalathas, A ; O'Keefe, N ; Lee, KL (IEEE, 2020-10-04)
    A high-speed indoor optical wireless communications link using few-mode based uniform beam shaping is experimentally demonstrated. Results show that high-quality uniform beam can be realized and the BER performance can be improved significantly by combining the signals from different channels supported by different modes.
