<p>A receiving method at a mobile terminal comprising performing communication by a code division multiple access (CDMA) using a spectrum diffusion, executing an arrival radio wave search for detecting radio waves from transmission lines with different delay times and synthesizing receiving signals from radio waves from different transmission lines using a rake synthesis, wherein, when a detected receiving status of a receiving signal satisfies a preset condition, a range of delay times for executing an arrival radio wave search is changed. For example, when a phasing pitch is used as a variation of a received electric field, a reciprocal of a phasing pitch is compared with a preset threshold value or a moving speed of a mobile terminal calculated from a phasing pitch is compared with the threshold value and, if the threshold value is smaller, a peak search is performed only in the vicinity of the peak determined by the previous search.</p> |
