The computational complexity and peak-to-average power ratio (PAPR) of conventional
precoded orthogonal frequency division multiplexing (OFDM) systems can be reduced using …

Selected mapping (SLM) schemes are widely used to reduce the peak-to-average power
ratio (PAPR) in orthogonal frequency-division multiplexing (OFDM) systems. Various time …

One of the biggest problems for orthogonal frequency division multiplexing (OFDM) systems
is the high peak-to-average power ratio (PAPR), which breaks the orthogonality among …

The recent advances and developments in Internet of Things (IoT) have enabled numerous
IoT applications in various sectors such as smart healthcare, industrial IoT and smart …

In this paper, a double-optimal partial transmit sequence (DO-PTS) for orthogonal frequency
division multiplexing (OFDM) is proposed. Through twice optimization for subblocks …

The aim of this letter is to share a novel concept termed pseudo-pilot, which offers a simple
and efficient approach of nonpilot-assisted channel estimation. Our key idea is to transfer the …

The destructive impact of fading environments and also bandwidth limitations are two main
challenges which communication is dealing with them. These challenges can affect on the …

Tone reservation (TR) is an attractive and widely used method for peak-to-average power
ratio (PAPR) reduction of orthogonal frequency division multiplexing (OFDM) signals, where …

To reduce the PAPR in OFDM systems selected mapping schemes (SLM) are widely used
due its distortion less nature. However a major drawback of traditional SLM technique is …
