The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

Information is carried by changing the phase of the carrier. ->BPSK (Binary PSK): Uses two phases (0° and 180°). Very robust, but only 1 bit per symbol. ->QPSK (Quadrature PSK): Uses four phases (0°, ...

We provide 4 datasets including the popular modulation methods in 5G and 6G. The datasets can be obtained by linking https://mailnwpueducn-my.sharepoint.com/:u:/g ...

The contemporary wireless communication system makes full use of the available spectrum by making it possible to adapt to various channel situations. The extremely well-organized multi-carrier ...

Abstract: Orthogonal frequency division multiplexing with index modulation (OFDM-IM), which transmits information bits through ordinary constellation symbols and indices of active subcarriers, is a ...

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 ...

Moving wireless local area networks (WLANs) to the 5-GHz band is very appealing because of the leap in data rates from 11 or 22 Mb/s to 54 Mb/s. But, making the leap to 5-GHz also means the use of ...

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 ...

Orthogonal frequency-division multiplexing (OFDM) is a method of transmitting data that uses modulation and multiple carrier frequencies to cope with conditions that would hinder a single-frequency, ...

One of the main advantages of OFDM is that it can achieve higher spectral efficiency, or the amount of data that can be transmitted per unit of bandwidth, than other modulation techniques. This is ...
