  Abstract

The simple mathematical equation, the conditional mutual information with Gaussian modulations, gives birth to non-orthogonal multiple access (NOMA). The equation requires the perfect successive interference cancellation (SIC) for one of two users. However, the existing modulation schemes do not guarantee the perfect SIC performance, for the entire operating range of power allocation, even though it is possible for the part of the whole range. Recently, new modulation techniques, such as polar on-off keying (POOK), make the equation hold for all power allocation factor [6]. This paper considers all two users perfect SIC performance. The equation does not guarantee the perfect SIC performance for one of two users. Therefore we pay the price for all users perfect SIC performance. It is shown that the price is less than an additional 3 dB power. In result, the trade-off between performance and power could be considered, with the plenty power of the base station.
