Parallel interference cancellation (PIC) principle is conceptually simple and yet eeective method of parameter estimation and data detection in the presence of multiple-access and multipath interference. It uniies some of the known methods of data detection, complex channel co-eecient estimation, as well as delay tracking in DS-CDMA receivers. The PIC method will be derived and some numerical r...

We consider the problem of delay estimation by observations solutions several SDEs. It is known that MLEs for these models are consistent and asymptotically normal, but likelihood ratio functions not differentiable w.r.t. parameter, therefore numerical calculation encounter certain difficulties. propose One-step Two-step MLEs, whose has no such problems provide an estimator equivalent to MLE.
