Acquisition performance decreased rapidly own to serious inter-symbol interference (ISI) caused by those complex channel with relatively large delay spread. An interference resistant adaptive threshold acquisition algorithm (IR-ATAA) for DS-UWB systems proposed here has the feature that the decision threshold changes automatically adapting to the signal to noise ratio (SNR) at time of comparison. The performance analysis mainly focus on the probability of correct acquisition (P_ACQ) and estimation error of timing delay (MSE) with IEEE defined standard channel models and in the presents of multi-access interference (MAI) which is assumed as an additive white Gaussian noise. The simulation results also indicate the superiority of IR-ATAA over the fixed threshold acquisition algorithm Performance Analysis of Adaptive Threshold Acquisition Algorithm in DS-UWB with Multi-path Environment Jun Chen Yong-Bo Zeng Zheng Zhou doi:10.1109/CHINACOM.2006.344808 Communications and Networking in China, 2006.
