PROPAGATION PATH ESTIMATION DEVICE, RECEIVER, AND PROPAGATION PATH ESTIMATION METHOD

摘要

Provided is a propagation channel estimation apparatus capable of obtaining a propagation channel estimation value at a high speed with high accuracy even in an environment where a propagation channel fluctuates fast when the propagation channel is estimated according to an adaptive algorithm. A path used to estimate a propagation channel estimation value is selected among a plurality of paths, the propagation channel estimation value of the path is first calculated, and an interpolation/extrapolation process is performed by using a result of the calculation. Accordingly, at the time of estimating the propagation channel according to the adaptive algorithm, even in the environment where the propagation channel fluctuates fast due to influence of a frequency error between a transmitter and a receiver or Doppler shift associated with movements of the transmitter and the receiver, it is possible to obtain the propagation channel estimation value at a high speed with high accuracy.
