Title
Performance analysis of RLS based channel estimation in UWB OFDM system
Abstract
Ultra Wideband (UWB) communication is one of the key technology for high data rate networks over short range communication. The ultra wide bandwidth offers pulses with very short duration that provides frequency diversity and multipath resolution. UWB OFDM communication is proposed for physical layer in the IEEE 802.15.3a standard which covers wideband communication for wireless personal area networks (WPANs). Channel estimation is very important for OFDM based UWB system because of its coherent demodulation and channel is time varying. This paper proposes a new blind adaptive channel estimation technique based on orthogonal iteration method for UWB OFDM communication. The channel parameters are adaptively estimated in the proposed method which is based on recursive least square method. The proposed method distinguishes itself from many previously reported channel estimation methods by eliminating the training bits, thereby increasing the channel efficiency. The proposed method is compared with LS based blind channel estimation method in various aspects by computer simulations.
