技术特点

NOMA superposes multiple users in the power domain although its basic signal waveform could be based on the orthogonal frequency division multiple access (OFDMA) or the discrete Fourier transform (DFT)-spread OFDM the same as LTE baseline.

SIC接收机

NOMA adopts a successive interference cancellation (SIC) receiver as the baseline receiver scheme for robust multiple access.

配套技术

To make NOMA promising, it should be used with advanced transmission/reception techniques such as dirty paper coding (DPC) or a SIC receiver

性能影响因素

power allocation for each UE greatly affects the user throughput performance and thus the modulation and coding scheme (MCS) used for data transmission of each UE
By adjusting the power allocation ratio, P1/P2, the BS can flexibly control the throughput of each UE.
