Introduction

This application note is developed for the ATA Ultra High Frequency (UHF) products and serves to increase RF sensitivity and the communication range of the ICs. This software is using Forward Error Correction (FEC) with (12, 8) Hamming-Code algorithm together with dedicated RX telegram setting.

Measurements from the laboratory show that, with this software, the sensitivity of the components can be improved by ~2 dB, depending on the data rate and other telegram settings.
