Bounds on timing jitter estimation in cooperative networks
Hani Mehrpouyan, Steven D. Blostein · 2010
Successful collaboration and resource sharing in cooperative networks require accurate estimation of multiple timing jitters. When combined with signal processing algorithms the estimated timing jitters can be applied to mitigate the resulting intersymbol interference (ISI) and improve performance. In this paper we seek to derive the Cramer-Rao lower bounds (CRLB) for timing jitter estimation in distributed cooperative networks. In addition to being a benchmark for judging the performance of timing jitter estimators, the CRLBs can be applied to determine the effect of the choices of training sequence and cooperative protocol on timing jitter estimation.
