中文摘要	正交频分(OFDM)传输以它很高的频谱利用率和抗多径的能力成为电力线通信的优选方案。针对电力线信道时域平稳的特点,该文提出一种新的比特分配算法,利用上次比特分配结果和当前信道特性进行OFDM子信道非迭代比特分配。连续实测的电力线信道的比特分配计算机仿真表明所提出的算法快速有效。该算法的计算复杂度优于典型的比特分配算法。; Due to its outstanding performance in frequency utilization and overcoming the multi-path fading,OFDM has been the optimal technology in power line communications.As the power line channel was stationary in time domain,a novel algorithm was proposed in this paper which utilizes the last time bit-loading results and the new channel characteristic to get the new scheme without iteration and the complexity of algorithm has been simplified dramatically.The new algorithm was tested by practical continuous measured data,and was proved to be correct and efficient.The complexity of this algorithm is analyzed and compared to the other typical bit-loading algorithms,the obvious advantage is shown.; 国家自然科学基金资助项目(50177016)~~
