ABSTRACT:
A CDMA adaptive antenna reception apparatus is provided. The apparatus includes N adaptive antenna reception sections and an initial antenna weight production section. Each of the reception sections includes an initial antenna weight selection section, which selects initial values from initial antenna weight candidates, an antenna weight control section, which adaptively controls antenna weights, and antenna weighting synthesis sections, each of which multiplies signals received by K antennae by the antenna weights and synthesizes the results of the multiplication to detect a desired signal. The initial antenna weight production section detects beam directions and null directions from antenna weights of desired signals. A null formation direction discrimination section estimates a null direction of a new desired signal, and an initial antenna weight candidate production section produces initial antenna weight candidates with which the null is formed in the estimated null direction in order to detect the new desired signal.
