Constant amplitude zero autocorrelation waveform

A Constant Amplitude Zero Autocorrelation (CAZAC) waveform is a type of signal used primarily in communications and radar systems. These waveforms are characterized by having constant amplitude and an autocorrelation function that has zero values at all non-zero time shifts. Essentially, this means that the waveform is designed to avoid self-interference at different time delays, which is desirable in many applications such as spread spectrum communication.
