| 摘 要： | 讨论了MUSIC测向算法在DSP上快速实现的一种方法。利用多级维纳滤波的方法求解信号特征矢量和信号空间维数,有效地减少了算法的运算量;同时利用TI公司高速DSP芯片(TMS320C6713)的可多流水线并行运行优势,实现了一种基于9元均匀圆阵的快速MUSIC测向方法。

| Abstract: | A fast realization method of MUSIC algorithm based on DSP is discussed.On the one hand,using multistage Wiener filter to estimate the dimension of signal subspace can reduce the computational complexity significantly.On the other hand,taking advantage of parallel operation and multi-pipelining of high-speed digital signal processor(TMS320C6713),MUSIC algorithm on uniformly circular array(UCA) with nine sensors is realized fast. |
