The Zadoff-Chu (ZC) sequence is a widely used preamble in RF communication systems, valued for its sharp correlation peak, constant amplitude, and periodic nature. This article explores its mathematical properties, performance under different parameters, and real-world applications, including robust frame detection in noisy environments. Experimental results with a Pluto SDR demonstrate the ZC sequence's effectiveness in identifying OFDM frame boundaries and recovering transmitted symbols reliably.
