Channel Equalization and Interference Analysis for Uplink Narrowband Internet of Things (NB-IoT) [PDF]
IEEE Communications Letters, 2017 We derive the uplink system model for In-band and Guard-band narrowband Internet of Things (NB-IoT). The results reveal that the actual channel frequency response (CFR) is not a simple Fourier transform of the channel impulse response, due to sampling rate mismatch between the NB-IoT user and Long Term Evolution (LTE) base station.
