Abstract
A spread spectrum radio transmission digital mobile communication device having RAKE receiving functions. By adding an arrangement of an adaptive antenna to control directivity of a receiving antenna to the spread spectrum radio transmission digital mobile communication device, it is possible to decrease influence of a co-channel interference wave and influence of a delay wave having a delay time smaller than chip time width in a diffusion signal, as not achievable by RAKE receiving functions.
