METHOD OF FILTERING DIGITAL SIGNAL FOR MAINTAINING DATA TRANSMISSION RATE IN TDD OR TDMA SYSTEM AND COMMUNICATION SYSTEM ADOPTING THE SAME

摘要

Provided is a digital filter implementing a function by using circular convolution of a digital input signal and a unit pulse response of the digital filter in applying a filter to the digital signal.;In addition, a configuration sequence change of an output signal, which occurs as a result of digital filtering according to the present invention, in comparison to an input signal, is corrected by inversely performing circular shifting in a transmitter by amount of the configuration sequence change, or by reconstructing a signal after making synchronization and acquiring the signal previous to a time point of the synchronization by amount of the configuration sequence change, in a receiver.
