Cascaded Multiwire-PLC/Multiple-VLC System: Characterization and Performance

This paper proposes a cascaded multiwire-power line communication (PLC)/multiple-visible light communication (VLC) system. This hybrid architecture offers low installation cost, enhanced performance, practical feasibility, and a wide range of applications. Novel analytical expressions are derived for key statistics and outage probability, bit error probability, and ergodic channel capacity metrics. Furthermore, the analytical results are validated through Monte Carlo simulations, with several performance curves presented under various channel and PLC/VLC system parameters. All expressions derived in this work are original and have not been previously published. Our proposed system proves feasible for smart environments, green communication systems, internet of things networks, industrial environments, and next-generation networks.

Receive Diversity for Differential Binary Noise Modulation

Differential binary noise (DBN) modulation encodes information in the polarity transition of a reused noise realization, dispensing channel state information and carrier-phase recovery. This letter proposes single-input multiple-output (SIMO) reception for DBN via post-correlation decision-statistic combining, followed by one zero-threshold decision. The combined statistic is a Hermitian quadratic form in complex Gaussian vectors, yielding an exact conditional bit error probability (BEP) with no Gaussian approximation. Averaging it over $κ$-$μ$ fading and the reused energy gives the exact BEP for arbitrary weights. Because that energy is shared, its deep fades are common to every branch, and the observation length caps the diversity order at $\min(Mμ,N)$. The deflection-optimal weights follow in closed form and interpolate soft combining and power weighting. Measured 65 GHz indoor non-line-of-sight (NLoS) results quantify the trade-off between spatial resources and observation length.
