Abstract:
    The method includes the following steps: distributing the sub-carrier number on the base of the power reduction value while the user adds a sub-carrier so as to decide the sub-carrier number needed by users; according to this decided number, calculating the mean bit number on a sub-carrier sent by all users; according to the power needed for sending this mean bit number, distributing the practical sub-carrier to all users. Via water injection algorithm of single user, the method carries out bit-loads for every user.
