This paper presents a novel, robust technique to estimate timing and frequency offset in an Orthogonal Frequency Division Multiplexing (OFDM) system without the use of pilot signals. We first present an overview of an OFDM system for high-speed wireless data communications [1], including the particular parameters chosen for our design. We then describe some prior attempts to estimate timing and...

The aim of this publication is to analyze the topic high-frequency jet ventilation (HFJV), namely catheter HFJV (C-HFJV), from a mathematical–physical as well clinical point view. There are known issues with applying anesthesia and artificial lung (ALV) during surgical procedures in upper airways, e.g., bronchoscopy or tracheostomy. principles, advantages, disadvantages discussed context basic ...
