摘要：
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 bit-error-rate (BER) and packet-error-rate (PER) performances to set the appropriate number of RAKE fingers If under the given requirement of the error rate criterion, applying channel estimation based on the proposed successive cancellation.
