The cross correlation method is a significant technique for time delay estimation. Firstly, the signal model of time delay estimation based on correlation is studied. Moreover, the arithmetic of digital signal processing is studied. Then, the real-time cross-correlation time delay estimation machine is realized based on MSP430 MCU, TMS320C54 series DSP and FPGA. It is shown by the pool examination results that the time delay estimation machine is effective.
