This paper deals with channel estimation and equalization, as well as noise variance
estimation in uplink narrowband-internet of things (NB-IoT) system. Different techniques are …

3GPP introduced Narrow-Band Internet of Things (NB-IoT) in release-13 with a special
feature to work with only 180 kHz bandwidth. Effective channel estimation is highly important …

In this paper, a novel low-complexity channel estimation algorithm with estimation error
suppression based on the conventional least squares (LS) method is proposed for downlink …

Efficient and low complexity channel estimation has become the prime concern in
Narrowband Internet of Things (NB-IoT) receiver performance. The maximum likelihood …

NB-IoT (Narrowband Internet of Thing) technology has been adopted as standard
technology of 3GPP. NB-IoT will be spread into various business model and be expected to …

Narrowband Internet of Things (NB-IoT) systems were specified by 3GPP in release 13 as a
low power wide area network (LPWAN) technology to operate with a very narrow bandwidth …

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 …

This paper presents a downlink channel estimation method intended for a Narrowband
Internet of Things (NB-IoT) access link. Due to its low computational complexity, this method …

We consider channel estimation (CE) in narrowband Internet-of-Things (NB-IoT) systems.
Due to the fluctuations in phase within receiver and transmitter oscillators, and also the …

An emerging narrowband radio technology named narrowband Internet of Things (NB‐IoT)
based on cellular communications has been standardised by the 3rd Generation …
