Description
NOMA serves multiple users on the same time-frequency resource by separating them in the power or code domain, with successive interference cancellation at the receiver. In the ISAC literature it appears as a multiplexing scheme that frees additional degrees of freedom for sensing while keeping communication throughput high — relevant background, but peripheral to the CSI-sensing core of this thesis.
When it's used
- ISAC waveform designs sharing spectrum across users
- Power-domain multiplexing analyses
- Capacity arguments in joint sensing-comms papers
Limitations
- SIC complexity grows with user count
- Sensitive to power-allocation errors
- Limited adoption in current Wi-Fi standards
