Downlink Performance Analysis of Pinching Antenna Systems: WDMA or NOMA?

Bingxin Zhang, Han Zhang, Kun Yang, Yizhe Zhao

In pinching antenna systems, NOMA delivers higher spectral efficiency at high SNR via successive interference cancellation while WDMA remains more reliable at low to moderate SNR but encounters outage floors.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The results show that NOMA achieves higher spectral efficiency at high transmit signal-to-noise ratio (SNR) due to successive interference cancellation (SIC), whereas WDMA offers more reliable performance at low to moderate SNR but suffers from an outage floor and rate saturation at high SNR.

C2weakest assumption

The unified channel model accurately captures antenna deployment, user spatial distribution, and path loss without significant unmodeled interference or hardware impairments that would alter the outage and rate expressions.

C3one line summary

In pinching antenna systems, NOMA delivers higher spectral efficiency at high SNR via successive interference cancellation while WDMA provides more reliable performance at low to moderate SNR but exhibits an outage floor and rate saturation at high SNR.
