1. a radio communication device is characterized in that:

  • possessArray antenna is made of a plurality of antenna oscillators;

    A plurality of related operation portion, the signal that receives at each antenna oscillator of above-mentioned array antenna is implemented the computing cross-correlation mutually with the signal that has pre-determined, and calculates the related operation value;

    The path test section detects the arrival path according to the output of above-mentioned a plurality of related operation portion and receives regularly;

    The path correlation synthesizes portion, calculates the complex conjugate that receives described related operation value regularly at detected described arrival path, generates correlation matrix or associated vector with described related operation value and described complex conjugate;

    AndPath receives bundle formation portion, with from being the inverse matrix of foundation with correlation matrix and be that the long-pending path of trying to achieve of column vector of element receives weight, form the directivity bundle to receive regularly the related operation value of calculating in described related operation portion at the arrival path as the output of the synthetic portion of described path correlation.
