PROBLEM TO BE SOLVED: To realize effective multiple accesses by assigning subcarrier according to conditions required in a communication of applications, regarding assignment method of subcarrier, in a communication system which uses OFDM as a modulation method. SOLUTION: This multiple access equipment is constituted, by including an application cognitive part, a communication path condition estimating part, a subcarrier assignment control part for assigning the right of usage to each user, in such a manner that the transmission speed of information, where subcarrier satisfying communication quality required in the communication is required, is satisfied; and an application subcarrier control part which stores subcarrier assigned to each of the users and transmits application subcarrier information to a primary demodulation part.
