Applications of OFDM in vehicular and indoor optical wireless communication
thesis
posted on 2017-02-17, 01:18 authored by Dissanayake, Sarangi DevasmithaOrthogonal Frequency division multiplexing (OFDM) is used widely in wired and wireless technologies. In this thesis, OFDM in two application areas are studied. The first area of study is, OFDM in wireless access in vehicular environment (WAVE) which is a radio frequency (RF) wireless technology. The other area of study is, OFDM in indoor optical wireless communication (OWC) which is an optical wireless technology. In OFDM in WAVE, a novel method is developed to accurately estimate the relative speed of vehicles using the OFDM symbols exchanged. In OFDM in indoor OWC systems, the limitations of existing OFDM modulation schemes such as diversity combined ACO-OFDM are investigated and ways to address those shortcomings are devised. Also in this thesis, a novel optical modulation scheme is developed, which shows higher optical power efficiency than the two conventional schemes: asymmetrically clipped optical OFDM (ACO-OFDM) and DC biased optical OFDM (DCO-OFDM).
