The Internet of Things (IoT) is transforming the whole of society. It represents the next
evolution of the Internet and will significantly improve the ability to gather and analyze data …

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 …

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 consider stochastic optimization of a smooth non-convex loss function with a convex non-
smooth regularizer. In the online setting, where a single sample of the stochastic gradient of …

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 …

Narrowband Internet of Things (NB-IoT) is a wireless standard and a novel technology for
the IoT devices and applications. The extended coverage, low cost and long battery life …

This paper presents new technique in OFDM systems for estimation of channel quality,
which is a crucial for improving communication system execution in the existence of noise …

Channel estimation is a mandate technique to enhance the performance of the OFDM
system so that the system can become robust to noise. To this end, several techniques have …
