MATLAB Program for Computing CHU Sequences

Based on D.C. CHU's algorithm for computing CAZAC sequences, we developed a MATLAB program to generate CHU sequences. The implementation includes calculation of autocorrelation functions, FFT-transformed CHU sequences, and key characteristics of CAZAC sequences. Additionally, we provide the original D.C. CHU algorithm document for reference.

The program utilizes MATLAB's signal processing toolbox for FFT operations and implements the core CHU sequence generation algorithm through vectorized operations for optimal performance. Key functions include chu_seq() for sequence generation and calc_autocorr() for correlation analysis.

Beyond the core implementation, we can expand this article to cover applications of CHU and CAZAC sequences in communication systems, particularly their importance in synchronization and channel estimation. We can provide detailed explanations of D.C. CHU's algorithm principles and computational steps, including MATLAB code snippets demonstrating each stage. Finally, we can compare alternative CAZAC sequence generation methods with D.C. CHU's approach, analyzing their computational complexity and performance advantages in practical implementations.
