Effects of Transmit Diversity on a Discrete Wavelet Transform and Wavelet Packet Transform-based Multicarrier Systems

Abstract: This paper proposes a MIMO-WPT-based multicarrier system with feedback from the receiver to the transmitter carrying the channel state information (CSI), whereby a steering matrix can be defined to enhance robust performance against multipath fading effects at the receiver. This relies on the timescale localization of wavelet bases, and is demonstrated in terms of bit error rate performance. In contrast to sinusoidal carriers WP have very narrow side lobes, with most energy contained in the main lobe; this mak… Show more
