As of the specification Release 13 completed by the 3rd Generation Partnership Project
(3GPP) in June 2016, narrowband Internet-of-Things (NB-IoT) has attracted great attention …

Single-tone and multi-tone transmissions in the narrowband Internet of Things (NB-IoT)
uplink system can be accomplished by employing different orthogonal basis. In this paper …

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 …

The Internet of Things (IoT) is gaining immense popularity in executing automation activities
via wireless connectivity in the modern era. The IoT networks are designed using mostly low …

One of the most important parameters in the performance of wireless communication
systems is the channel estimation. However, apart from the usual OFDM modes, there are …

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 …

As specified in Release 13 specification of the 3rd Generation Partnership Project (3GPP),
narrowband physical uplink shared channel (NPUSCH) is a critical physical layer …

Narrowband Internet of Things (NB-IoT) was introduced by 3GPP in low power wide area
network to support low power and wide coverage applications. Since it follows long term …

The Internet of Things (IoT) devices are finding their way into nearly every aspect of modern
day life, as a result, their applications are increasing exponentially. This increased demand …

The central challenge in supporting massive IoT connectivity is the uncoordinated, random
access by sporadically active devices. The random access protocol and activity detection …
