Abstract
Disclosed are a channel estimation method and a channel estimation apparatus, and a receiver using the same. The channel estimation apparatus provided in the receiver detects pilot signals from radio signals and estimates channels of the detected pilot signals. The channel estimation apparatus estimates channels corresponding to data by conducting linear interpolation, which allows for simultaneous interpolation in time and frequency axes, by use of information on the estimated pilot channels. Thus, the memory capacity required for the receiver can be reduced using channel estimation in which the simultaneous interpolation is conducted. Also, the performance of the receiver can be further improved in a wireless environment where the receiver moves at high speed.
