BackgroundPreoxygenation with tidal volume breathing for 3 min is commonly used technique. An end tidal expiratory oxygen concentration greater than 90% is considerd to be adequate for preoxygenation. The aim of this study was to check the effects of

In this letter, we consider outer-loop link adaptation, wherein we pursue to find the optimum modulation and coding scheme (MCS) that provides the maximum throughput without directly estimating the channel state. We cast this problem in a form of mul

In this paper, we present a new approach for beam alignment in millimeter wave high speed train systems. The core idea of our approach is using Bayesian multi-armed bandit in the beam search process. In the proposed method, by approximating the signa

License Assisted Access (LAA) LTE (LAA-LTE) is a new type of LTE that aggregates the licensed LTE bands with the unlicensed bands via carrier aggregation. To operate in unlicensed bands, LAA-LTE adopts the listen-before-talk policy and designs its ch

In this paper, we present a performance analysis of large‐scale multi‐input multi‐output (MIMO) systems for wireless backhaul networks. We focus on fully connected N nodes in a wireless meshed and multi‐hop network topology. We also consider

This paper proposes non-orthogonal multiple access (NOMA) schemes to fulfil the 5G requirements of high spectral efficiency and massive connectivity. The proposed NOMA schemes utilize UE signatures in code domain and frequency domain. In particular,

This paper considers a low complexity codebook-based beam searching algorithm for massive MIMO (Multiple Input Multiple Output) systems in limited scattering environments. Based on the asymptotic property of the massive MIMO systems that the channel
