Abstract:
The increasing demand for wireless connectivity and subsequently larger bandwidth requirements for high capacity connections have stretched the physical limits of existing wireless technologies in terms of bandwidth availability across the wireless frequency spectrum. Numerous research methods have been investigated and introduced in current wireless devices to overcome the problems relating channel capacity restriction. Some of these solutions are antenna diversity techniques such as multiple-input multiple-output (MIMO), and frequency diversity methods such as orthogonal frequency-division multiplexing (OFDM). In this thesis, orbital angular momentum (OAM) is successfully generated to transmit uncompressed high-definition (HD) video content at 4 Gbps rate over a 60 GHz wireless channel. As a prediction method, MA TLAB simulation was employed to design and create holographic plate (HP) masks and spiral phase plates (SPP). The MATLAB code was further utilized to control a printed circuit board (PCB) router drill to generate any desired models on copper or dielectric plates for example, holographic masks. It is believed for the first time, an experimental setup is exploited for generation of a 4 Gbps uncompressed video link over 60 GHz OAM wireless channel, and results are confirmed in tern:1s of received signal power and data rate throughput to illustrate the existence of OAM in 60 GHz channel. The achievements of this research wi~l contribute to the field of knowledge and it is concluded that it is a feasible prospect for multi-gigabit wireless communications to be achieved over OAM channels while improving the spatial diversity and spatial multiplexing of the wireless channel.
