碩士 / 國立暨南國際大學 / 通訊工程研究所 / 95 / Abstract Channel estimation for Orthogonal Frequency Division Multiplexing (OFDM) systems, which is widely used in today’s wireless communication systems, has been extensively studied under the assumption of time variation and multipath propagation [1]. Channel estimation has been an important issue for the performance of OFDM systems. In practice, pilot signals are transmitted by OFDM systems over some of their subcarriers for the purpose of channel estimation. Wh...

Besides, another mechanism is proposed to extending the phase noise tolerance. The biggest problem of the conventional 1-tap equalizer is that it will enhance the noise while correcting the received signal once the singular channel occurs. Hence, we propose a pilot-based adaptive channel equalization that will update the channel information every OFDM symbol....

Historically, children were considered to rarely experience sleep problems and daytime sleepiness in middle childhood (5 – 12-years of age), however more recent findings indicate this may have changed. Psychosocial and environmental factors, such as technology use and bedtime routines, have been associated with reduced sleep quantity and/or quality. Links have also emerged between shorter sleep duration in children, and an increased risk of obesity in childhood and adulthood. Although a number o...
