Implementing OFDM modulation The following sections discuss implementing cyclic prefix insertion and removal for OFDM modulation and demodulation. FFT and inverse FFT operations The most ...

Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about ...

A proposed Extensible SOQPSK modulation waveform brings the best of both OFDM modulation and single-carrier SOQPSK modulation to telemetry applications.

Index modulation (IM) in orthogonal frequency division multiplexing (OFDM) systems represents a transformative approach in modern communications. This technique utilises the indices of active ...

OFDM modulation is then applied to the frame by using an inverse fast Fourier transform (IFFT), a GI is added, and the OFDM frame is output as an IF (intermediate frequency) signal.

It’s too difficult to create components with the peak-to-average power ratio (PAPR), gain flatness, and the efficiency needed for OFDM at mmWave frequencies and extreme bandwidths. The 802.11ad ...

OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers, while being sent simultaneously. This results in the optimal usage of bandwidth. A set of orthogonal sub-carriers ...

MagnaCom Opens NGMN 2015 with Live Demonstration of the World’s Highest Performance OFDM Modulation for 5G Cellular Networks ...

It made use of both DSSS and OFDM modulation found in “a” and “b”, and like previous standards, used 20MHz of bandwidth on the 2.4GHz spectrum for data connectivity.
