Abstract: OFDM is playing a more and more important role in wireless communication systems. Unfortunately, it is not trivial to conduct a performance analysis of OFDM systems. Therefore, it is highly ...
Abstract: This paper presents channel measurement results obtained in a bus for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM ...
前回、より多くの情報を送ることができる通信方式として多値変調について解説しました(6月13日の記事参照)。同じように多くの情報を一度に送る通信方式として「マルチキャリア」があります。 マルチキャリアとは簡単にいえば、複数の搬送波 ...
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 ...
The non-orthogonal multiple access (NOMA) scheme has been recognized as a promising candidate for future generation wireless communication networks that require a high data rate and spectral ...
CableLabs has announced the certification of the industry’s first DOCSIS 3.1 Plus (DOCSIS 3.1+) device supporting four orthogonal frequency-division multiplexing (OFDM) channels. The certified device, ...
This repository contains the reference implementation for “Challenger‑Based Combinatorial Bandits for Subcarrier Selection in OFDM Systems.” It frames OFDM subcarrier selection as a Top‑m ...
Introduction: Underwater acoustic (UWA) communication systems confront significant challenges due to the unique, dynamic, and unpredictable nature of acoustic channels, which are impacted by low ...
