MULTI-CARRIER TRANSMISSION DEVICE, MULTI-CARRIER RECEPTION DEVICE, AND MULTI-CARRIER RADIO COMMUNICATION METHOD

摘要

There are provided a multi-carrier transmission device, a multi-carrier reception device, and a multi-carrier radio communication method capable of improving the throughput of the entire multi-carrier radio communication system. According to a reception SNR value for all the sub-carriers 1 to 4 of users 1 to 4 in the reception SNR table created, the number U(n) of users who can use the sub-carrier is calculated. The sub-carrier n* which can be used by the minimum number of users U(n) is searched. In the searched sub-carrier n* which can be used by the minimum number of users U(n), the user k* having the maximum reception SNR value is searched. The sub-carrier n* is assigned to the user k*.
