摘　　要：在超宽带无线通信中,频率依赖性信道扭曲了发射脉冲波形,影响了通信系统的性能。文章分析此类信道模型下脉冲位置调制和脉冲幅度调制的性能,结果表明,在频率依赖性信道中PAM调制优于PPM调制。Frequency dependence channel distorts transmited pulse and this affects the perlormance of the communication sistem in ultra-wideband wireless communication. This paper has analyzed the performance of PPM and PAM under frequency dependence channel model, the results have shown that the PAM is better than the PPM in frequency dependence channel.
