Claim One:
1. A joint decoder and synchronizer for operating on an input signal modulated with encoded data, having an iterative processor comprising: a synchronization processor operative for receiving and synchronizing to input channel observations associated with the input signal; a decoder operative for decoding synchronized channel observations received from the synchronization processor and producing an associated indication of decoding success; a feedback loop supplying the indication of decoding success to the synchronization processor; the synchronization processor further operable for adjusting its synchronization to the channel observations based on the indication of decoding success; and wherein the synchronization processor further comprises a soft decision aided synchronization processor operative for computing a synchronization parameter based on the indication of decoding success, the soft decision aided synchronization processor further operative for computing a corrected channel observation based on the input channel observations and the synchronization parameter.
