A frame-level synchronization (FLS) algorithm for the UWB transmitted-reference (TR) receiver is designed and analyzed in this paper. The algorithm exploits the robustness of the TR receiver to synchronization errors [1], and has a moderate accuracy but a very low complexity and fast synchronization speed compared to conventional approaches requiring subnanosecond-level accuracy. Detailed analysis of the algorithm is carried out. Synchronization performance of both blind and non-blind approaches are derived and compared in terms of the average acquisition time. Error detection and correction strategies are built in to further improve the performance of the algorithm. Parameter selections that minimize the average acquisition time are also discussed, based on our in-depth analysis.

This work proposes an effective code acquisition technique for Galileo BOC signals, exploiting a fast parabolic interpolator running on three estimated ambiguity samples in the neighbourhood of the coarse estimate. Performance analysis is carried out in comparison with the conventional approach, based on the power detector test. The numerical results, obtained from wide simulation trials under operating settings, have evidenced that the devised method outperforms the conventional approach for all the timing offsets and is well suited for satellite spread spectrum communications.

“…The performance of an acquisition scheme is generally evaluated in terms of the mean acquisition time, probability of successful acquisition within a given time, and/or implementation complexity. Since the mean acquisition time of a sliding correlator-type acquisition scheme increases linearly in proportion to the required sample size by the fixed sample size test, it can be used for the purpose of performance evaluation (refer to (8) in [26]). In general, the required sample sizes for hypotheses and are different from each other, except when .…”

We propose robust acquisition schemes for chip time-synchronous direct-sequence spread-spectrum (DS/SS) signals in wide-band pulse jamming. To mitigate the performance degradation due to the impulse-like wide-band jamming signal, the received signal is preprocessed by employing simple order statistic filters. We consider the use of two types of median filtering schemes: a running median filter operating at a chip rate and a block median filter processing the received signal sampled at an oversampling rate. For analytic design, the partial correlation of median filtered pseudonoise (PN) signals is approximated by a piecewise linear model using an upper bound. The analytic design is verified by computer simulation. Finally, the acquisition performance of the proposed schemes is compared to that of conventional schemes.
