Keyword多相滤波器 Fir Ip Core 高效谱分析射电天文谱线信号
Abstract在详细分析了多相滤波器组原理和实现方法后,通过在DSP Builder下调用FIR IP Core(Finite Impulse Response Intellectual Property Core,有限冲击响应滤波器知识产权核)构建了一个多相滤波器组,实现了对输入信号的抽取式下变频的同时减低了等效采样带宽,进而使FFT(Fast Fourier Transformation,快速傅里叶变换)的处理带宽减低,在同等变换N点数的情况下有效地提高FFT通道的利用率和谱分辨率,提高倍数取决于抽取因子M,该设计能广泛使用在射电天文的谱线信号的精细分析同时也提高了处理器速度和性能。
