Novel metamaterial and metamaterial-inspired structures and microwave/antenna applications thereof are proposed and studied in this thesis. Motivated by the challenge of extending the applicability of metamaterial structures into practical microwave solutions, the underlying obj…
In this thesis, our goals are to optimize and analyze essential parameters for pilot-assisted spread spectrum systems with different types of diversity and optimization criterion. For a multipath fading channel with different types of power delay profile, the partial RAKE receiv…
Space-time block codes alone generally have little or no coding gain. To extract coding gain, space-time block codes have been previously concatenated with an outer trellis to generate simple and powerful codes, known as super-orthogonal codes. This work has two main themes: it …
To adapt to the adverse radio environment efficiently, we investigate the use of two code division multiple access (CDMA) based broadband systems. In one of these systems, information symbols are transmitted simultaneously and in other system, information symbols are chip-interl…
The growing adoption of data communication has resulted in dramatically higher capacity and performance. Communications engineers have historically optimized Physical (Phy)/Medium Access Control (MAC) layers to increase aggregate network throughput. However, in recent years, res…
The Republic of Lebanon has to change its dominant State-Owned Enterprises to Private- Owned-Enterprises through privatization. The increase in public debt to GDP ratio and budget deficit to GDP ratio urges the country to set an immediate fiscal reform plan. Privatization interv…
Future wireless communications systems need a high quality of service coupled with high data rate transmission for multimedia services. Achieving this goal in the hostile wireless environment with its limited spectrum has several challenges and implies the necessity of a communi…
