Performance Enhancement of Multiple-Input Multiple-Output OFDM-Based wireless Systems

Orthogonal frequency division multiplexing (OFDM) is an attractive multicarrier transmission technique for wideband communications because it effectively transforms the frequency selective fading channel into a flat fading channel. Hence, OFDM provides greater immunity to multipath fading and impulsive noise, and eliminates the need for complicated equalizers. Furthermore, the combination of multi-input multi-output (MIMO) signal processing techniques with OFDM is regarded as a promising solution to give a good performance and support high data rate transmission in the next-generation wireless communication systems. However, OFDM communication systems have two primary drawbacks. The first is the high sensitivity to carrier frequency offsets and phase noise. The second, and the major aspect we are concerned with, is the high peak-to-average power ratio (PAPR) of the transmitted signals. The high PAPR makes OFDM sensitive to nonlinear distortion caused by the transmitter power amplifier (PA), and hence lead to degradation in the system performance.

     The work in this thesis can be divided into three main parts.

MSc. thesis

Performance Evaluation of a CDMA Wireless Local Loop Networks

In the telephone network, the circuit between the subscriber's equipment and the local exchange is called the local loop. Wireless Local Loop (WLL) is the use of radio to make a connection from a local switch or a distribution point in the fixed network to a number of homes. WLL provides reliable, flexible, and economical access to the local telephone service using radio technology in the place of traditional wireline.

CDMA technology has the potential to provide a significant improvement in the capacity of cellular radio systems compared with FDMA and TDMA systems. However, this improvement is dependent upon the effectiveness of the power control system, especially on the reverse link.
