We present an adaptive bit loading algorithm for orthogonal frequency division multiplexing (OFDM) systems. Present algorithm use a blockwise allocation of modulation and power levels to the subcarriers with puncturing of «weak» subcarriers. The simulation results show the effectiveness of this algorithm for the case of random multipath Rayleigh channel.
