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, 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; 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; generating one or more data channel estimate weights using said reference signal channel estimate weights; selecting a data detector using said reference signal channel estimate weights, said data channel estimate weights or both; and detecting said data signal using said selected data detector, wherein said selected data detector uses said reference signal channel estimate weights, said data channel estimate weights or both.

1. A method of channel estimation and data detection in a wireless communication system, comprising:
receiving a signal, wherein said signal is composed of a data signal, a desired reference signal and an interference reference signal from an interfering cell; selecting a channel estimator to generate channel estimate weights for said desired reference signal, said interference reference signal or both; generating one or more reference signal channel estimate weights for said desired reference signal, said interference reference signal or both, using the selected channel estimator; generating one or more data channel estimate weights using the one or more reference signal channel estimate weights; determining whether the one or more data channel estimate weights indicate significant interference from the interfering cell; selecting a data detector based on whether the one or more data channel estimate weights are determined to indicate significant interference from the interfering cell; and detecting said data signal using said selected data detector.
