The demand for reliable high rate and efficient communication is ever increasing. In this thesis we look at two diverse issues in such devices, as well as their feasible solutions. In recent years orthogonal frequency division multiplexing (OFDM) has gone from a promising data transmission technique to become a mainstream technique used in several current [...]
Study Comparison of WCDMA and OFDM
Wideband Code Division Multiple Access (WCDMA) is one of the main technologies for the implementation of third-generation (3G) cellular systems. It is based on radio access technique proposed by ETSI Alpha group and the specifications was finalised 1999. WCDMA is also known as UMTS and has been adopted as a standard by the ITU under [...]
Wireless OFDM Communication Systems
Title: Peak to Average Ratio Reduction in Wireless OFDM Communication Systems Future mobile communications systems reaching for ever increasing data rates require higher bandwidths than those typical used in today’s cellular systems. By going to higher bandwidth the (for low bandwidth) flat fading radio channel becomes frequency selective and time dispersive. Due to its inherent [...]
