Abstract

In this paper, we introduce a successive cancellation channel estimation scheme based on the preamble structure suggested in the DS-UWB proposal of IEEE P802.15.TG3a. In order to improve the transmission efficiency, we reduce the length of preamble defined in the proposal without sacrificing the channel estimation performance. The gain on the transmission efficiency is discussed for different data rates. In addition, we present the packet-error-rate (PER) and bit-error-rate (BER) performances to set the appropriate number of Rake fingers under the given requirement of the error rate criterion, applying channel estimation based on the proposed successive cancellation. A performance comparison of the finger combining methods of maximal-ratio-combining (MRC) and equal-gain-combining (EGC) applying the proposed preamble is also presented.
