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: The increasing need of high data rate transmissions over fading channels has drawn attention to modulation schemes with high spectral efficiency such as the multidimensional rotated MPSK/QAM ...

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 ...

Orthogonal frequency division multiple access (OFDMA) is a version of OFDM (orthogonal frequency division multiplexing) modulation that happens to be optimized for multiple users, specifically for ...

Abstract: Orthogonal Frequency Division Multiplexing with Index Modulation (OFDM-IM) has emerged as a remarkable modulation technique, combining OFDM and index modulation to achieve high spectral ...

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 ...

This repository contains a MATLAB simulation of Fast Orthogonal Frequency Division Multiplexing with Index Modulation (Fast-OFDM-IM), a next-generation waveform combining Fast-OFDM and subcarrier ...
