APPARATUS AND METHOD FOR RECEIVER BASED ON EQUALIZER IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A receiver operation method based on an equalizer and an apparatus thereof for reducing the loss of reception performance in a mobile communication system are provided to reduce the size of a multiple tap and reduce the complexity of hardware. CONSTITUTION: A channel estimator(107) presumes a channel about a multiple path reception signal. The channel estimator analyzes a delay profile of a multiple path channel. The channel estimator changes the location of multiple tap according to the result of a delay profile result. The channel estimator comprises the multiple tap sub channel estimator and the channel estimation controller. The multiple tap sub channel estimator obtains the channel estimation value of the multiple tap from the multiple path received signal.
