A CDMA adaptive antenna reception apparatus which allows high speed initial convergence of an antenna weight is disclosed. The CDMA adaptive antenna reception apparatus includes N adaptive antenna reception sections, and an initial antenna weight production section. Each of the adaptive antenna 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 a plurality of antenna weighting synthesis sections each of which multiplies signals received by K antennae by the antenna weights and synthesizes results of the multiplication to detect a desired signal. The initial antenna weight production section which detect beam directions and null directions from antenna weights of desired signals being received by the adaptive control of the adaptive antenna reception sections, a null formation direction discrimination section which estimates a null direction of a new desired signal, and an initial antenna weight candidate production section which produces initial antenna weight candidates with which the null is formed in the estimated null direction in order to detect the new desired signal.
