Orthogonal frequency-division multiplexing (OFDM) waveforms are common in telecommunications and echoes from targets can be compared with a transmitted signal to isolate phase-shifts related to ...

In this letter, we propose a unified framework for PAPR reduction and digital predistortion (DPD) by optimizing the waveform of the OFDM signal. We develop two effective and low-complexity algorithms ...

Run the JCRSimulation.m script for the full simulation. Range-Doppler maps for PMCW and OFDM waveforms. Target detection and velocity estimation results. Constellation diagrams and BER performance ...

Dr. Khoirul Anwar is the founder and the patent owner of orthogonal frequency division multiplexing based 4G technology ... transmission block to eliminate data distortion caused by wave interference.

With a fresh wave of spinoffs in the works, it’s a good time to brush up on some harsh financial realities. Whether for reasons related to ego, pay or simplistic growth, most bosses want to ...

Frequency is a measure of the number of vibrations a sound wave makes per second. For example, a sound measured at 4,000 Hz vibrates 4,000 times per second. The frequency, which is the pitch of a ...

BERLIN (Reuters) - The German military will establish a new division tasked exclusively with territorial defence, the army said on Saturday, bringing all existing reserve units under direct army ...

Index modulation (IM) is an innovative technique that enhances the performance of Orthogonal Frequency Division Multiplexing (OFDM) systems, which are widely used in modern communication technologies.
