Pulse Non-Orthogonal Multiple Access (PNOMA) Technique for Future Generation Wireless Networks

Abstract

The foundation of Non-orthogonal multiple access (NOMA) is providing services to several consumers at once while using the same resource in terms of frequency, time, and area. In this research, we provide a novel approach to reducing complexity and power consumption by using ideas from pulsed NOMA systems. The strategy is quite versatile and may be used with numerous other systems. The improvement that we suggest differs from the OFDM system in that the amplitude shaping pulse of the OFDM modulation uses pulses with duty cycles. The time domain spectrum of the modulated signals is spread out by pulsing NOMA symbols, resulting in a spreading gain that is inversely proportional to the duty cycle of the pulsed subcarriers. We show that the additional diversity may be completely utilized by a pulsed-NOMA receiver without the need for OFDM receivers. It is demonstrated that while pulsed NOMA receivers outperforms with OFDM receivers, it also offers advantages over NOMA receivers in terms of intrinsic low complexity and low power consumption.
