Reception ratios

WebbThis article presents an independently developed packet reception algorithm, which drastically improves the physical performance of LoRa communication links. The advanced signal presence detection, synchronization, and symbol detection strategies are shown to significantly increase packet reception ratios in extremely adverse noise conditions. http://user.it.uu.se/~frehe489/publications/wennerstrom13longterm.pdf

WebbBased on the computation, several ratios, d f, are related to the PRR and, d r, to the acknowledgment reception ratio (ARR).

Webbexample, irrespective of the packet reception ratios of the links, if the average of the link pairs is very high (close to 1.0), then us-ing a protocol that does not code works better than using a network coding protocol. Measuring on several 802.15.4 and 802.11 testbeds, we find that it varies significantly across network topologies and link ... john greed discount codes uk https://wilhelmpersonnel.com
