Implicit Pilots for an Efficient Channel Estimation in Simplified Massive MIMO Schemes with Precoding by Mário Marques da Silva, Rui Dinis, João Guerreiro

“…This paper proposes a new channel estimation scheme based on implicit pilots, optimized for a simplified massive multiple input, multiple output (MIMO), implemented with precoding, combined with Single-Carrier with Frequency-Domain Equalization (SC-FDE) modulations. We propose an iterative receiver that considers an iterative detection with interference cancellation and channel estimation. …”

Intermittent Atrioventricular Block following Fingolimod Initiation by E. Gialafos, S. Gerakoulis, A. Grigoriou, V. Haina, C. Kilidireas, E. Stamboulis, E. Andreadou

“…A 47-year-old female patient with multiple sclerosis (MS) developed symptomatic intermittent 2nd degree atrioventricular block (AVB) of five-hour duration, five hours after the first two doses of fingolimod, that resolved completely. Frequency domain analysis of heart rate variability (HRV) revealed increased parasympathetic activity and decreased sympathetic tone, while modified Ewing tests were suggestive of impaired cardiac sympathetic function. …”
