<P>PROBLEM TO BE SOLVED: To provide radio communications equipment for suppressing interference between adjacent base stations, without impairing the effects of the distribution of transmission symbols. <P>SOLUTION: The radio communications equipment includes the steps where a transmission symbol is duplicated from each transmission symbol, the preliminarily applied number of transmission symbol groups are generated, and the transmission symbol groups are assigned by the region units of the number of time slots; P (P is an integer of 1 or larger, and M or smaller) and the number of frequency sub-carriers; Q(Q is an integer of 1 or larger, and N or smaller) in frames of the number of time slots; M (M is a positive integer of 2 or larger) and the number of frequency subcarriers; N (N is an integer of 2 or larger), and the transmission symbol assigned to each frequency sub-carrier of each time slot is multiplied by a code system, consisting of N pieces of elements by which each transmission symbol assigned to each frequency subcarrier is multiplied, while cyclic is shifted by the number of frequency sub-carriers; Q by each frame time slot, and the multi-carrier modulation and transmission of each transmission symbol group multiplied by the code system is performed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
