A two-step search scheme for rapid and reliable UWB signal acquisition in multipath channels
We propose the two-step search scheme with linear search based second step (TSS-LS) by improving the conventional two-step search scheme with bit reversal search based second step (TSS-BS) for rapid and reliable acquisition of ultra wide band (UWB) signals in multipath channels. The proposed TSS-LS utilizes two different thresholds and search windows to achieve fast acquisition. Furthermore, unlike the TSS-BS in which the bit reversal algorithm is applied in both steps, the linear search is adopted for the second step in the proposed TSS-LS to correctly find the starting point in the range of effective delay spread of the multipath channels, and to obtain reliable bit error rate performance of the UWB systems.
