Visible-light communication (VLC) is an emerging technology utilizing light-emitting diodes and photodetectors (PDs) cameras [i.e., image sensors (ISs)] as the transmitter receivers (Rx), respectively, for simultaneous data communications, illumination, localization, sensing in indoor optical Internet of Things. We propose a single-input–multiple-output (SIMO) hybrid VLC system using PD-based I...

Feature-based physical layer authentication (PLA) schemes, using position-specific channel characteristics as identifying features, can provide lightweight protection against impersonation attacks in overhead-limited applications like e.g., mission-critical and low-latency scenarios. However, with PLA-aware attack strategies, an attacker maximize the probability of successfully impersonating le...

The effectiveness of classroom reality orientation (RO) in dementia was evaluated by conducting a systematic literature review. This yielded 43 studies, of which 6 were randomized controlled trials meeting the inclusion criteria (containing 125 subjects.) Results were subjected to meta-analysis. Effects on cognition and behavior were significant in favor of treatment (cognition standardized mea...

In this paper, we study FPGA implementation of a novel supra-optimal receiver diversity combining technique, generalized maximal ratio combining (GMRC), for wireless transmission over fading channels in SIMO systems. Prior published results using ML-detected GMRC diversity signal driven by BPSK showed superior bit error rate performance to the widely used MRC combining scheme in an imperfect ch...
