Over the coming years, it is expected that the number of machine-to-machine (M2M) devices
that communicate through long term evolution advanced (LTE-A) networks will rise …

Cell search and synchronization in the Third-Generation Partnership Project (3GPP) Long-
Term Evolution (LTE) system is performed in each user equipment (UE) by using the primary …

Mobile devices perform cell search for initial access in cellular-based industrial Internet of
Things (IoT) systems. Existing fifth-generation (5G) new radio (NR) cell-search scheme …

Next generation wireless networks will exploit the large amount of spectrum available at
millimeter wave (mmWave) frequencies. The design of mmWave systems, however, is …

Fundamental issue exists in a wireless communication system is how to allocate a number
of users within a limited spectrum resource. This leads to the development of promising …

This article investigates the advantages and disadvantages of cell search for LTE and NR.
This investigation enables us to design a couple of synchronization signals specified in …

The physical random access channel (PRACH) in the uplink of cellular systems is used for
the initial access requests from users. In fifth generation (5G) systems three different types of …

Random Access is an important aspect of mobile systems where multiple users are always
competing for resources. However, noise and interference imposes a significant problem to …

In the LTE system, uplink synchronization can be established through the random access
channel, by which timing and frequency offsets between transceivers can be estimated and …

Compressed sensing (CS) algorithms can be used to perform beam alignment in mmWave
phased arrays with fewer channel measurements by exploiting the sparsity of mmWave …
