Slow Wave Activity During Nocturnal Sleep in Hypersomnolence Disorder

Journal of Sleep Research, EarlyView.
ABSTRACT Slow waves during non‐rapid eye movement (NREM) sleep are associated with the restorative aspects of sleep. Previous research has suggested reduced normalized slow wave activity (SWA), particularly in the first cycle of NREM sleep, as a feature of hypersomnolence disorder (HD); however, the scarcity of existing research highlights the need for

Performance comparison between Gaussian interleaver, Rayleigh interleaver, and dithered golden interleaver

Annales Des Telecommunications/Annals of Telecommunications, 2008
This paper is a proposal for a new form of random interleaver for a turbo code based on the probability distribution of channel statistic model of transmission, instead of a uniform probability distribution. In our work, we use the normal (Gaussian) and Rayleigh probability distribution in accordance with the channel type and compare them with classic ...
