摘要
提出了一种基于小波的UWB脉冲波形设计方法,根据FCC规定的辐射掩蔽来调整小波函数的各项参数,选择一组小波函数作为基函数,依据线性最小均方误差准则(LMMSE)选取基函数的组合系数,从而得到一个组合小波脉冲。仿真结果表明,该脉冲宽度具有纳秒量级,频谱很好地满足了FCC的辐射掩蔽。
Abstract: A pulse waveform design method for UWB communication is presented. Wavelet functions are chosen as base func- tions. The diverse translation factors and diverse spectral moving factors of wavelet are selected according to the FCC emission mask. Under the principle of linear minimum mean square error ( LMMSE), the weighting factors are generated,
