The issue of data-aided joint carrier frequency offset (CFO) and channel estimation is investigated in the presence of a rapidly time-varying frequency-selective channel. We derive novel joint CFO/channel estimators for two cases: known and unknown channel statistics. The CFO estimator that makes use of known channel statistics is shown to attain the(More)
We present a detection scheme for multiple-symbol DPSK for use in a statistically unknown time-varying channel. The scheme relies on a parametric representation of the timevarying channel, resulting in a reduction in the number of parameters required to be determined by optimizing a maximum likelihood sequence estimation (MLSE) type cost function. We also(More)
