Abstract

In the paper, we propose a scheme of determining the number of subcarriers for MC-CDMA systems. Considering that the next-generation wireless communication system is expected to provide multimedia transmission services including speech, data, video and image etc and different services with diversity QoS requirements, we propose a QoS level judging algorithm based on multilayer fuzzy decision policy with multifactor. Then we give the expression of the number of subcarriers according to the QoS level of a user.
