BLER estimation of NB-IoT narrowband physical uplink shared channel
According to various forecasts, by 2025 the number of devices connected to IoT networks in one way or another will be from 25 to 50 billion. Given the multitasking of IoT systems, a large number of technologies are required to implement them, including radio technologies, which explains the need for research in the field of noise immunity and noise immunity. NB-IoT is recommended to cellular operators to deploy IoT networks because of a number of features and regulations in the regulatory framework. In this work, the MATLAB software simulated the operation of the downlink narrowband physical channels under various transmission parameters and subcarriers distance, calculated the BLER depending on the signal-to-noise ratio, and presented a comparison of the obtained results and their estimation.
