OFDM is a technique used in modern broadband wireless communications systems. To mitigate the effect of dispersive channel distortion in high data rate OFDM systems, CP is introduced to eliminate ...

Abstract: Ambient backscatter communication has emerged as a promising paradigm for ultra-low-power wireless systems. To support diverse IoT applications, backscatter communication should support high ...

Abstract: Though meaningful progress has been achieved for mobile wireless networks with the development of orthogonal frequency division multiplexing (OFDM) modulation, the reliability and ...

下の図は、OFDMの変調・復調の大まかなブロックダイアグラムです。これは、広く情報が公開されている802.11a無線LANのものをベースに作った図です。実際には、インターリーブなど他にも処理が入るのですが、ここではOFDMの概念を説明するために省略して ...

This repository provides MATLAB simulations for analyzing hostile wireless channels. You will explore important features such as Rayleigh fading, Doppler effects, and ...

In powerline communications (PLC), OFDM makes better use of bandwidth than FSK. Fast, reliable, and secure communications are critical for enabling the "energy Internet," an interconnected network of ...

LTE is likely the most complex wireless system ever developed. It incorporates features that could not have been economically implemented as recently as a decade ago. Today, with large-scale ICs, LTE ...
