In [[signal processing]], a '''Constant Amplitude Zero AutoCorrelation waveform''' ('''CAZAC''') is a periodic [[complex number|complex]]-valued [[signal (electrical engineering)|signal]] with modulus one and out-of-phase periodic (cyclic) [[autocorrelation]]s equal to zero. CAZAC sequences find application in wireless communication systems, for example in [[3GPP Long Term Evolution]] for synchronization of mobile phones with base stations. [[Zadoff–Chu sequence]]s are well-known CAZAC sequences with special properties.
