Orthogonal Frequency Division Multiplexing for Wireless Communications

Orthogonal frequency division multiplexing (OFDM) is a promising technique for high-data-rate wireless communications because it can combat inter-symbol interference (ISI) caused by the dispersive fading of wireless channels. The proposed research focuses on techniques that improve the performance of OFDM based wireless communications and its commercial and military applications. In particular,...

Orthogonal Frequency Division Multiplexing over Multimode Optical Fibers

Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation technique which is already widely employed in both wireless communication systems (WLAN, DVB-T, WiMAX) as well as wireline systems (ADSL, VDSL, PLC). Due to highly increasing speeds and lower costs of electronics, OFDM has recently also gained much interest in optical communication systems. In this paper, we will dis...

Orthogonal Frequency Division Multiplexing Timing Synchronization in Multi-Band Orthogonal Frequency Division Multiplexing Ultra-Wideband Systems

Problem statement: MB-OFDM UWB systems have attractive features and received a great attention. It has the capability of sending/receiving data at rates in access of 100 Mbits sec. Owing to the sensitivity of OFDM systems to synchronization errors, a fast synchronization algorithm is required to discern for the start of OFDM symbol. Existing approaches to OFDM time synchronization rely on their...
