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

摘要

A mutlicarrier transmitting apparatus, a multicarrier receiving apparatus and a multicarrier radio communication method, which are capable of improving a throughput of a whole multicarrier radio communication system. Based on receiving SNR values of users 1 to 4 for all of the subcarriers 1 to 4 in a receiving SNR table made, the number of available users U(n) of each subcarrier is calculated. Subcarriers n* having the smallest number of the available users are searched, and a user k* showing the highest receiving SNR value among the researched subcarriers n* having the smallest number of the available users U(n) is searched. Subsequently, the subcarriers n* are allocated to the user k*. <IMAGE>
