Analysis of Alternative Metrics for the PAPR Problem in OFDM Transmission
, 2011 The effective PAPR of the transmit signal is the standard metric to capture the effect of nonlinear distortion in OFDM transmission. A common rule of thumb is the log$(N)$ barrier where $N$ is the number of subcarriers which has been theoretically ...

Experiences of Person‐Centred Care Among Nurses in COVID‐19 Wards: A Qualitative Study
Nursing Open, Volume 12, Issue 8, August 2025.ABSTRACT Aim While there is extensive research on nurses' experiences in caring for COVID‐19 patients, studies focusing on person‐centred care in this context remain limited. This study aimed to obtain a thorough understanding of the meaning and essence of person‐centred care experienced by nurses in COVID‐19 wards in South Korea.

Fractional Fourier Domain PAPR Reduction
High peak-to-average power ratio (PAPR) has long posed a challenge for multi-carrier systems, impacting amplifier efficiency and overall system performance. This paper introduces dynamic angle fractional Fourier division multiplexing (DA-FrFDM), an innovative multi-carrier system that effectively reduces PAPR for both QAM and Gaussian signals with ...

New PAPR Reduction Method for Spatial Modulation [PDF]
The Journal of Korea Information and Communications Society, 2014 In this paper, a new peak-to-average power ratio (PAPR) reduction method for spatial modulation(SM) is presented. By using the matrix with all non-zero elements to precode the signals before transmitting, the transmit power is scattered over all transmit antennas for achieving the goal of PAPR reduction.
