EQUALIZER RECEIVING DEVICE IN A MOBILE COMMUNICATION SYSTEM AND A METHOD THEREOF, CAPABLE OF COPPING WITH DETERIORATION OF ADAPTIVE EQUALIZER HAVING A LIMIT OF CHANNEL ESTIMATION IN A SINGLE CELL ENVIRONMENT

摘要

PURPOSE: An equalizer receiving device in a mobile communication system and a method thereof are provided to maximize a channel estimation performance and an equalizer performance of a receiver by buffering and re-permitting a signal which is interference-removed when repetitively adapting an equalizer and removing interference.;CONSTITUTION: A matched filter(120) match-filters a signal received from an antenna(101). A control circuit generates different phase information about other cell of at least one cell of oneself. A multi cell pseudo-random noise generating device(420) generates a pseudo noise codes about the cell based on phase information. The multi cell channel estimator(410) uses the pseudo noise codes and the filtered signal and estimates channel estimating value about the cells. The multi cell adaptive equalizer uses the channel estimation value, models a signal transmitted from the cells and similar random signals and generates a filter coefficient. An equalizer finite impulse response filter(170) uses and equalizes the filtered signal and the filtered coefficient.;COPYRIGHT KIPO 2011
