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 ...

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 ...

Curtiss-Wright’s E-SOQPSK (Extensible SOQPSK) is a software-configurable, ultra-low-power Wi-Fi modulation scheme. Its waveforms offer some beneficial performance attributes for aeronautical telemetry ...

The CP-OFDM modulation scheme will have many options. Variable subcarrier spacing (SCS) will be 3.75, 15, 30, 60, 120, 240, 480 kHz with sub-1 GHz of 15 and 30 kHz and sub-6 GHz of 15, 30, and 60 kHz, ...

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 ...
