Detection Techniques in Uplink Massive MIMO Systems
TL;DR: In this article, the authors discuss the fundamentals of massive MIMO detection and also provide an overview of some of the recent state-of-the-art detection techniques, which are capable of achieving BER performance close to that of the ZF/MMSE detectors with comparatively less computations.
Proceedings ArticleDOI
Comparative Analysis of Low Cost Photodetectors for Visible Light Communication
TL;DR: Experimental results indicate that PD exhibits superior performance over solar panel in terms of sharp rise and fall time, however, the bit error rate performance of solar panel is better than that of PD for the given setup.
Journal ArticleDOI
Iterative Signal Detection for Diffusion-Based Molecular Communications
TL;DR: This paper uses weighted sum to enhance the received signal-to-ISI plus noise ratio (SINR) by exploiting the apriori characteristics of the diffusion channel impulse response and an iterative method estimates the ISI in a frame using the block-wise data symbol detection and adds this estimated ISI before the signal detection.
Proceedings ArticleDOI
Towards Zero-Crosstalk-Margin Operation of Spectrally-Spatially Flexible Optical Networks using Heterogeneous Multicore Fibers
TL;DR: It is shown that heterogeneous multicore fibers of specific core designs can achieve zero-XT-margin and a core-type selection method is proposed to minimize XT-margin in SS-FONs.
Proceedings ArticleDOI
Performance Analysis of OTFS Over Multipath Channels for Visible Light Communication
TL;DR: In this paper, the performance analysis of OTFS over multipath VLC channels has not been investigated and the performance of VLC based system is limited by dispersive characteristics of the VLC channel, and restricted modulation bandwidth of light emitting diode (LED) to mitigate the ISI, orthogonal time frequency space modulation is proposed in the literature.
