Equalization of OFDM signals using pilot carriers
All modern wireless communications include applications based on high data rates. Applications such as wireless LAN, wireless multimedia, wireless video conferencing involves high-speed data transfer. ^ O&barbelow;rthogonal F&barbelow;requency D&barbelow;ivision M&barbelow;ultiplexing is a promising technique for achieving high data rate and combating multipath fading in wireless communications. The main principle of this transmission technique is to divide the available channel bandwidth in to various subchannels, and transmit data in parallel on all subchannels. This transforms a frequency selective fading channel into flat fading channels, which eases the equalization. ^ The main aim of this thesis is to improve the performance of the OFDM system using pilot carrier equalization in a time-varying multipath channel and also assessing the performance of this equalization method in an AWGN channel. This thesis is an extension of the work done by Jukka Rinne and Markku Renfors . ^
