基于TMS320C54x系列DSP的长序列线性相关算法及实现
The Arithmetic of the Long Sequence Linear Correlation and Its Implementation Based on DSP of TMS320C54x Series
【摘要】 提出一种使用快速相关法的长序列相关算法,并使用DSPL IB库函数设计FFT系数表,实现了两个1024点实序列的线性相关运算.与直接相关法相比,这种方法容易实现,且运算速度快,有较高的应用价值.
【Abstract】 An arithmetic to calculate correlation of two long sequences is introduced by using a fast correlation method,and the FFT coefficient table with DSPLIB library function is designed.At last two 1024-dot real sequences’ linear correlation operation was accomplished.Compared with the direct correlation method,this method is easier,rapider and more practical.
