Recently, orthogonal non-orthogonal multiple access (O NOMA) with polar on-off keying (POOK) has beenproposed to mitigate the severe effect of the superposition. However, it is observed that the performance of theO NOMA strong channel user is better than that of the perfect successive interference cancellation (SIC), i.e., theperformance of a single user transmission with binary phase shift keying (BPSK). Can the performance of theBPSK modulation be better that that of itself? It is not normal. It should be clearly understood theoretically, withthe ultimate bound, i.e., the channel capacity. This paper proves that the channel capacity of the O NOMA strongchannel user is non-zero with zero power allocation. Thus, it is shown that the interference is transformedeffectively into the meaningful signal.
