Narrowband Internet of Things (NB-IoT) and LTE Systems Co-Existence Analysis [PDF]

2018 IEEE Global Communications Conference (GLOBECOM), 2018
In this paper, we establish a comprehensive uplink system model for in-band and guard-band Narrowband Internet of Things (NB-IoT) with arbitrary sample duration in the NB-IoT device. The mathematical expressions of received LTE and NB-IoT signals are derived.
