Abstract

Abstract: In order to characterize a multi-path channel accurately，this paper proposes a fractional Brownian model of OFDM at an arbitrary sampling rate.To establish this model，it uses the characteristics of pilot in OFDM，and considers the prior condition that multi-path fading obeys the Rayleigh or Rice distribution.For model building，it analyzes the fractal characteristic of wireless channel based on fractal.The simulation results indicate that this model is more accurate than the statistical model in characterizing the multi-path channel.

Key words: channel model, Orthogonal Frequency Division Multiplexing（OFDM）, fractal, statistic, fractional Brown model

摘要： 为了更准确地刻画多径信道，提出了任何采样率下的OFDM信道的分数维布朗模型。模型利用OFDM中具有导频符号的特点，考虑多径衰落具有服从Rice或Rayleigh分布的先验条件，从分形学角度出发分析无线信道的分形特性，建立模型。仿真结果表明，该模型比统计模型更准确地刻画多径信道。
