In the V-BLAST OFDM system, if bits and power are allocated among all subchannels on average, the bad subchannels will deteriorate system performance largely. Based on this, adaptive V-BLAST OFDM system is proposed. And the water filling algorithm based on bisection iteration method is introduced. Simulation results show the proposed system satisfies the target BER and it outperforms the traditional one in spectral efficiency
