A comparative PAPR, BER, and PSD for optical NOMA communication framework

PAPR reduction using SLM-PTS-CT hybrid PAPR method for optical NOMA waveform

“…The original NOMA signal is divided into N sub-blocks, each containing M samples. The signal at the sub-block is denoted as where represents the sub-block index, and n represents the time index [ 53 ] : For each sub-block, a set of phase factors is generated for each partition within the sub-block. Let's consider that each sub-block is divided into P partitions.…”
