Although orthogonal frequency-division multiplexing (OFDM) is a widely accepted waveform
in many standards and is expected to keep its dominance in future 5G systems with various …

Orthogonal frequency division multiplexing (OFDM) signals with rectangularly windowed
pulses exhibit low spectral confinement. Two approaches usually referred to as pulse …

Orthogonal frequency division multiplexing with index modulation (OFDM-IM) employs the
indices of the active subcarriers for information transmission, as an alternative to …

When the channel state information is available, frequency-domain precoding is studied for
rectangularly-pulsed orthogonal frequency-division multiplexing (OFDM) using cyclic prefix …

This paper tackles the problem of the signal‐to‐noise ratio estimation for cyclic prefix (CP)‐
