An Adaptive Channel Quality Metric for Ultra-Narrowband Systems
Tomaž Šolc, Carolina Fortuna · 2018
In this paper, we propose an adaptive channel quality metric that is suitable for uplink channel estimation in ultra-narrowband networks. The proposed metric relies on channel measurements rather than on packet information, therefore it doesn't need a large number of packets to initialize, and is simple enough that can be computed per channel for a large number of channels. Our results show that the proposed metric should be able to identify channels with the least amount of interference for a wide range of expected received packet powers.
