In this article, we applied Deep Learning on LTE-A uplink channel estimation system. The work involved creating of two SC-FDMA databases for training and for test, based on three types of channel propagation models. The first section of this work consists of applying an Artificial Neural Network to estimate the channel of SC-FDMA link. Neural Network training is an iterative process which consists on adapting the values of its parameters: weights and bias. After training, the Neural Network was ...

System throughput and resource utilization can be
improved in ultra-dense networks (UDN) by deploying a large number of small
base stations. However, base stations are very close in UDN, which will cause
serious interference between base stations. To solve this problem, coordinated
multi-point (CoMP) has been improved, which has the ability to reduce inter-cell
interference and to improve data rate. How ...

The explosive growth of the mobile traffic demand
has triggered the investigation of 5th generation mobile networks (5G) for the
future development of wireless communications. The ultra-dense network (UDN) has the ability to
effectively improve system throughput and spectrum utilization by deploying a
large number of low-power, low-cost, low-power home base stations or micro base
stations. The ...

Abnormal application behavior in mobile can produce a number of
undesirable effects. An incorrect or insufficient implementation of application
lifecycle, memory related issues and malicious application might cause an
unexpected behavior of the application such as bad usability, not responding,
crashed and even data loss. Current analysis and detection of abnormal
applications behavior are still not comprehensive enough where behavior under
user visible failure category such as crash, “stopped u...

This paper proposes a scheme of combining low-density parity check (LDPC)
code with unitary space time modulation (USTM) for noncoherent
multiple-input-multiple-output (MIMO) transmitter and receiver over Rayleigh block
fading and additive white Gaussian noise (AWGN) channel. The main aim is to
design the low complexity coded noncoherent MIMO receiver which is completely
dependent on the structural feature of unitary space-time matrix without
sending the pilot symbol at the transmitter and estim...

The whole globe is covered universally by water with a majority space. In
view of extraction of minerals as well as national security reasons, underwater
communication has become quite important for all the mankind. Researchers,
around the world are working for optimizing the multiple scheme in acoustic
channel. Recently, the researchers have reported valuable employability of IDMA
scheme in acoustic communica ...
