摘要
在某水声阵列信号处理中,为了提取在高采样率下采集得到的24通道4载波窄带阵列信号的特征,减小运算量以适应实时信号处理要求,提出了阵列信号的“二次解调”算法;对两种实现解调的方法进行了比较,分析了在不同情况下计算量和占用存储器资源的差别,从而为“二次解调”的实现选择合适的处理算法;结合浮点数字信号处理器TMS320C6713中8指令并行运行的特点,实现了基于TMS320C6713的“二次解调”实时处理算法。
In order to obtain the characteristics of 24 narrowband sonar array signal acquired by high sample frequency and decrease operations quantity so as to meet real--time processing, the twice demodulation algorithm is presented and two methods to realize the above algorithm are compared. Lastly, the twice demodulation real- time processing algorithm is realized in the float digital signal processor TMS320C6713, which has the capacity to run 8 instructions in parallel.
