Abstract:
In receiving radio waves from a transmitter by an array antenna, and estimating an arrival direction of a direct wave, delay times of the arriving waves are estimated ( 13 ) by means of a super-resolution process based on transmission channel estimation results, an arriving wave component corresponding to the delay time having been determined to be equal to or longer than a threshold value is removed ( 15 ) from the transmission channel estimation results, arriving wave components after the removal are separated from each other to extract direct wave components ( 17 ), and an arrival angle is estimated ( 19 ). The arrival direction of the direct wave can be accurately estimated in an environment where delayed waves of short delay times are present. Also, the amount of calculation is small even when the super-resolution process is performed.

Claim (Index 13):
The receiving apparatus as set forth in  claim 4 , further comprising a delay time number discrimination unit for determining whether the number of the delay times estimated by the delay time estimation unit is smaller than a predetermined number, wherein\n when the number of the delay times is determined to be smaller than the predetermined number, said delay time grouping unit does not carry out the determination as to whether the delay time is shorter than the threshold value, and each of said first to N-th delayed wave removal units does not carry out the removal of the arriving wave.
