On the Performance Evaluation of Variable-Dwell Time PN Acquisition Systems
Yu T. Su, Charles L. Weber · 1984
The variable dwell time (VDT) acquisition algorithm has been proposed to reduce the mean acquisition time [1,2] of a PN waveform. Previous analyses pertaining to VDT systems have used either approximation methods [1-3] or simulations [4] to evaluate related system performance parameters, namely, PD, PFAand n, the mean dwell time per cell. We present two related algorithms to compute these parameters. Exact results are obtained by these algorithms. Furthermore, PFAand n can be evaluated more efficiently.
