Abstract
The degradation in bit error rate performance due to imperfect subcarrier tracking by the Demodulation Synchronization Assembly (DSA) is investigated. Results apply to any type of digital loop and received signal dynamics, A type four loop causes the least amount of loss, because it tracks phase jerk with zero steady-state error. However, when f and f are as large as in the extended Magellan mission, it will be necessary to decrease the loop update time in order to minimize the losses. Figures 2 through 8 illustrate numerical results of this analysis.
