Time Delay Estimation Algorithm Based on Cross-Power Spectrum

In implementing the cross-power spectrum based time delay estimation algorithm mentioned in this paper, we provide a detailed description of its simulation results. The algorithm implementation involves computing the cross-power spectrum between two signals using Fast Fourier Transform (FFT) operations, followed by phase extraction and time domain conversion through inverse FFT. Through this algorithm, we achieve accurate signal time delay estimation, with results visualized using comprehensive plotting functions that generate multiple charts demonstrating the estimation performance. These charts clearly illustrate the precision and reliability of the time delay estimates, showing minimal variance across multiple simulation runs. The detailed analysis of simulation results enables deeper understanding and evaluation of the performance characteristics and advantages of the cross-power spectrum based time delay estimation approach, including its robustness to noise and computational efficiency compared to traditional correlation-based methods.
