IPC: H04N7/12
Filed: 1998-10-27
Abstract: PURPOSE: A device for updating tap coefficients of a channel equalizer is provided to improve channel equalizer efficiency by altering step size according to time varying channel condition. CONSTITUTION: A device for updating tap coefficients of a channel equalizer adopts an LMS(Least Mean Square) algorithm. In the channel equalizer, the difference of a basis signal and an output of an adoptive equalizer(2) becomes error signal. The adoptive equalizer(2) calculates input signal and tap coefficients and compensates the channel distortion of input signal. The compensated input signal is sliced by a slicer(5). An error signal calculator(7) receives the sliced signal from the slicer(5) or exercise row from basis signal generator(6) and subtracts the compensated input signal from received signal. The result is sent to an error signal normalizer. The normalizer adjusts the step size depending on time varying channel condition. A field synchronized signal, a first segment of input signal in the error signal normalizer, moves error signal and updates tap size. A moving calculator transfers the updated tap size to adoptive equalizer.
