Nowadays, there is an intention to merge different types of data into a single vivid
presentation. By combining text, audio, images, video, graphics, and animations, we may …

This paper studies the key aspects of an optical link which transmits a broadband microwave
filter bank multicarrier (FBMC) signal. The study is presented in the context of creating an all …

Due to the Internet of Things (IoT) requirements for a high-density network with low-cost and
low-power physical (PHY) layer design, the low-power budget transceiver systems have …

This paper reviews efficient amplification techniques, such as a load modulation, an
envelope tracking (ET), an envelope elimination and restoration (EER), an outphasing and a …

In this paper, we present and evaluate a low-cost platform, able to emulate multiple primary
and secondary users with a single Software Defined Radio (SDR) device. By effectively …

In recent days intense research is taking place on energy efficiency (EE) of a multi-user
wireless network. In this paper we propose a model to detect EE based on limited user traffic …

Abstract Multi-carrier phenomenon Orthogonal Frequency Division Multiplexing (OFDM) is
considered to be one of the most significant developments in wireless communication. It is …

The dissertation is devoted to radio-fibre systems in which optical fibres are used to
distribute the signals of wireless standards eg inside a building. The construction of such …
