Abstract: PROBLEM TO BE SOLVED: To obtain an improved estimation strategy by estimating a channel impulse response, estimating data in a signal by using it, repeating this process at least one time by using an output, providing improved channel impulse response estimation and performing it by using correlation channel measurement in this case. SOLUTION: A switch 1 selects a pseudo training sequence about respective repeating after the first passing. The sequence is obtained by formatting a data bit and the original training sequence bit to an actual burst structure. In the case of decision feedback from an equalizer output, a slicer 16 selects an input signal in an output of a data estimating part 11 and offers an output signal to a line 5. In the case of feedback from a decoder output, the switch selects a signal in an output of a channel decoder 13.

Abstract: A method and apparatus for estimating channel impulse response and data in a signal transmitted over a channel in a communication system. The channel impulse response is estimated uses correlative channel sounding, and then, using the estimated channel impulse response, the data in the signal is estimated. The output is then fed back to the channel impulse response estimator and the channel impulse estimation is repeated. The data estimation and channel impulse response estimation may be iterated a number of times.
