摘要： Provided is a method and system for estimating a channel in a wireless communication system. An interference coefficient is calculated based on a known structure of a pilot, and a channel value in a frequency domain is estimated. A channel value in a time domain is obtained by transforming the channel value in the frequency domain and the channel delay values are subtracted from the channel value in the time domain, thereby cancelling interference.
