CHANNEL ESTIMATION AND DATA DETECTION IN A WIRELESS COMMUNICATION SYSTEM IN THE PRESENCE OF INTER-CELL INTERFERENCE

摘要

Channel estimation and data detection in a wireless communication system in the presence of inter-cell interference is provided. In one embodiment, a method for channel estimation and data detection in a wireless communication system, comprising receiving a signal (501 ), wherein said signal is composed of a data signal, a desired reference signal, and an interference reference signal; selecting a channel estimator using said desired reference signal, said interference reference signal, or both (502); applying said selected channel estimator to said desired reference signal, said interference reference signal, or both to generate one or more reference signal channel estimate weights (503, 504); generating one or more data channel estimate weights using said reference signal channel estimate weights (505); selecting a data detector using said reference signal channel estimate weights, said data channel estimate weights, or both (506); and detecting said data signal using said selected data detector (507, 508), wherein said selected data detector uses said reference signal channel estimate weights, said data channel estimate weights, or both.
