Simulation of different OFDM system synchronization using FPGA.
Abstract:This work focuses on the synchronization in orthogonal frequency division multiplexing (OFDM) systems, which arises to be one of the most critical operations. The OFDM system is explained in details and the synchronization problems occurring in this system are classified with the techniques used to overcome these problems. These techniques are 1-“maximum likelihood estimation” for timing and frequency offset, 2-the “Schmidl and Cox” timing and frequency offset estimation, and 3-synchronization of IEEE 802.11a standard signal or wireless LANs (WLAN).

Analysis of adaptive downlink multiuser mimo wireless communication system.
Abstract:Multiple-input multiple-output (MIMO) wireless communication systems have received significant attention due to their enormous channel capacity potential in rich scattering environment. Such systems need to consider multiuser transmission / reception in their design. This thesis investigates theoretically the ergodic capacity of multiuser MIMO systems operating with adaptive techniques to enhance their performance.
