In this paper, we present a new modulation scheme based on polynomial phase signals (PPS) for non-orthogonal multiple-access (NOMA) transceivers. The PPS leading to outstanding spectral efficiency are exploited to modulate the signal of users in the NOMA system. The demodulation procedure is performed by High-Order Ambiguity Function (HAF)-based successive interference cancellation (SIC). The performance evaluation, such as bit error rate (BER) and peak-to-averagepower ratio (PAPR) analysis of our new NOMA technique, is also demonstrated in this paper. Simulation results illustrate that the proposed scheme has the capability to increase the BER performance while suppressing the peak-to-average-power ratio (PAPR) compared to the traditional OFDM-based NOMA system or other existing modulation schemes.
