Abstract:

A key issue of modern Wi-Fi is providing ultra-high reliability jointly with high throughput. The issue becomes especially challenging when a Wi-Fi access point receives several data streams from multiple client stations. In this paper, we propose a novel approach to improve the performance of Wi-Fi receivers for uplink non-orthogonal multiple access in the presence of additive white Gaussian noise and phase noise. Our solution incorporates a low-complex smoothing technique at the equalization stage and the frame format to mitigate the effects of inaccurate frequency synchronization. Experimental results demonstrate a 4% average improvement in frame receive ratio at an 11 dB signal- to- noise ratio level of the weaker frame in uplink transmission.
