✦ Synopsis

We point out that the derivation of the Cramer-Rao lower bound for estimating a circular arc center and its radius by Chan and Thomas ( Graphical Models Image Process . 57, 1995, 527-532) has some problems although the final result is correct. Examining the mathematical structure of the problem carefully, we first correct their mistakes and then present a suitable formulation for the problem. We show that the result can be extended to more general problems including line and conic fitting.

## Abstract Exact closed‐form expressions of the Cramer–Rao bound (CRB) for joint sampling clock offset and channel taps are obtained in multi‐carrier code division multiple access systems. CRB is undoubtedly the most well known variance's bound to determine. It provides a benchmark against which w
