Abstract
A plurality of receiving sections are arranged within a single receiving unit. For instance, a first receiving unit 11a is equipped with two receiving sections 12a and 12c. For example, in the case that a failure happens to occur in the first receiving unit 11a, the base station is arranged in such a manner that another receiving section 12b belonging to a diversity receiving system of the same sector is located in a second receiving unit 11b operated under normal condition. As a result, even when a failure happens to occur in any one of arbitrary units, the receiving functions of the respective sectors can function as a single branch under normal condition, although the diversity gain is lowered.
