Claim:
1. A system for estimating non-energy parameters of an input signal, the system comprising: a) a third order digital phase locked loop (PLL) that tracks the input signal and includes: b) wherein the system is implemented in a receiver, and wherein the receiver is configured to calculate a full phase of the NCO, using the LF outputs φ c) a low-pass filter (LPF) inputting the output z d) wherein the receiver is further configured to generate a preliminary estimation of signal parameters using:  where  {circumflex over (φ)}  {circumflex over (ω)}  {dot over ({circumflex over (ω)})} e) wherein the receiver is further configured to generate an output J  where T f) wherein the receiver is further configured to jerk-correct the preliminary estimates by using the output z
