摘要
对宽带相干信号子空间算法(CSM)的基本原理作了简单介绍,对CSM算法的并行分解进行了深入研究,将算法最耗时的聚焦变换、特征分解和谱峰搜索分解为可以同时处理的各个部分,并在4片TI公司的高速DSP芯片(TMS320C40)上并行实现,最后给出了CSM算法并行处理的硬件实现框图。并行处理的优点是能大大提高算法的运算速度,从而满足算法的实时性要求。
The coherent signal-subspace method （CSM） ofbrodband signals is introduced, and the parallel decomposition of CSM is deeply analyzed. Focused transforming, characteristic decomposion and searching for the peak values, which are the most timeconsuming parts of CSM, are decomposed into different parts that can work simultaneously. A parallel realization are carried out in 4 pieces of TI Corporation＇s high speed DSP chip （TMS320C40）, and the chart of hardwares implement are displayed. A parallel realization can greatly improve the operating speed and satisfy the demand for real time.
