his research aims at creating broadband tunable, fully integrated filters for the application of
cognitive radio and signal classification receivers. The approach under study is the N-path filter
technique which is capable of translating a baseband impedance to a reference frequency creating
a tunab ...
Wireless communications is rapidly becoming one of the ubiquitous technological
underpinnings of modern society (such as electric power, fossil fuels, automobiles,
etc.).Fewpeoplethinkaboutthetechnologywithintheirmobilephones,remotecontrols,

This book is a result of the recent rapid advances in two related technologies: com-
munications and computers. Over the past few decades, communication systems
have increased in complexity to the point where system design and performance
analysis can no longer be conducted without a significant lev ...
The investigation of the propagation channel is becoming more and more important in mod-
ern wireless communication. The demand for spectral efficiency motivates exploitation of
all channels that can possibly be used for communications. Nowadays, a common trend for
designing physical layer algorithm ...
The single-carrier frequency division multiple access (SC-FDMA)
system is a well-known system that has recently become a preferred
choice for mobile uplink channels. This is attributed to its advantages
such as the low peak-to-average power ratio (PAPR) and the use of
frequency domain equalizers. Lo ...
This paper presents a Hidden Markov Model (HMM)-based speech
enhancement method, aiming at reducing non-stationary noise from speech
signals. The system is based on the assumption that the speech and the noise
are additive and uncorrelated. Cepstral features are used to extract statistical
informati ...
Ultra-wideband (UWB) technology enables high data-rate short-range communica-
tion, in excess of hundredmegabit-per-secondsand up to multi-gigabit-per-seconds,
over a wide spectrum of frequencies, while keeping power consumption at low lev-
els. This low power operation results in a less-interfering ...
Heterogeneous Network (HetNet): A network that consists of a mix of macro cells and low-power
nodes, e.g. Pico, Femto, Relay Node (RN) and Remote Radio Head (RRH)
A wireless communication network can be viewed as a collection of nodes, located in some domain, which
can in turn be transmitters or receivers (depending on the network considered, nodes may be mobile users,
base stations in a cellular network, access points of a WiFi mesh etc.). At a given time, s ...
I love telecommunications. It is powerful and it empowers, with
far-reaching consequences. It has demonstrated the potential to transform
society and business, and the revolution has only just begun. With the invention
of the telephone, human communications and commerce were forever changed: Time ...
