Analysis of GFDM as a robust 5G communication technique in noisy environment [PDF]
, 2020 One of the challenges of modulation techniques used in Fifth-Generation (5G) is their robustness in noisy environment. Conventional Orthogonal Frequency Division Multiplexing (OFDM) cannot be considered as a 5G waveform in its original form because of ...

Peak-to-average power ratio of good codes for Gaussian channel [PDF]
, 2014 Consider a problem of forward error-correction for the additive white Gaussian noise (AWGN) channel. For finite blocklength codes the backoff from the channel capacity is inversely proportional to the square root of the blocklength.

PAPR reduction in LTE network using both peak windowing and clipping techniques
Journal of Electrical Systems and Information Technology, 2019 Multicarrier technique orthogonal frequency division multiplexing (OFDM) modulation is a solution to provide high-speed and secured data transmission requirement in 4G technologies. Peak-to-average power ratio (PAPR) is one major drawback in OFDM system.
