Rafi Reter

A system and method for enhancing the reception of a single carrier signal. The single carrier signal includes periodic training signal and data. The system includes a transmitter configured such that L symbols of either the beginning or end of the N symbols of the training signal, where L&#x3c;N, are duplicated at either the end or the beginning of the training signal, respectively. The system further includes a receiver configured to receive the modified training signal for the calculation of FIR coefficients in a single pass and without the need for least mean square (LMS) methods or the like.

A method for reducing a ghost constituent of a composite video signal. The composite video signal includes a teletext data lines constituent. The method includes the step of detecting and processing two teletext data line constituent so as to obtain a ghost induced error. The method of further includes the step of utilizing the ghost induced error for calculating filter coefficients and applying the composite video signal to a filter having the filter coefficient for obtaining deghosted composite video signal.
