Abstract
This paper develops the theory for assessing the tracking performance and designing carrier synchronization loops which are to be matched to an unbalanced QPSK signal design. It is assumed that the power split and the 
and 
channel data rates are arbitrary. Bit synchronization is assumed unavailable for both carrier reconstruction techniques which have been suggested via MAP estimation theory. Numerical results are presented along with their comparison with results given in Part I where bit timing was assumed known.
