Abstract: A new DAB algorithm model with constraints of given transmission rate and QoS requirement is proposed in the paper, as well as be applied to OFDM system. Compared with the conventional equal bit allocation method, the DBA method can improvethe system performance greatly by analysis and numerical simulation.
