Abstract:
1. A channel estimation device that calculates a channel estimation value of data symbols of using pilot symbols in a channel in which said data symbols and said pilot symbols are time multiplexed, said channel estimation device comprising: weighting factor generating means for dividing data symbols in a slot of said channel into a plurality of data symbol sections, each of which includes a plurality of data symbols, selecting for each data symbol section pilot symbols suitable for calculation of a channel estimation value of the data symbols in the data symbol section, and generating for each data symbol section weighting factors which are to be used for weighting and averaging the pilot symbols and which vary from data symbol section to data symbol section in a slot; and channel estimation value calculating means for weighting and averaging said pilot symbols using said weighting factors, thereby calculating channel estimation values of the data symbols in the data symbol sections, wherein each channel estimation value is calculated in the weighting and averaging such that multiple weighting factors are used and each weighting factor is applied to multiple pilot symbols, and wherein each channel estimation value commonly corresponds to all of the data symbols in a single data symbol section among the plurality of data symbol sections in the slot of said channel.
