Abstract :
We derive the Cramer-Rao Bound (CRB) on the performance of joint estimators for timing offset, carrier phase offset, and carrier frequency offset for use in a QPSK packet-based communication link. It is shown that the CRB is a function of the pilot or training sequence, the signal-to-noise ratio (SNR), and the pulse shape. We also compute QPSK training sequences of different lengths that minimize the CRB for each of the parameters.
