In mathematics, a polyphase sequence is a sequence whose terms are complex roots of unity:

a n = e i 2 π π q x n {\displaystyle a_{n}=e^{i{\frac {2\pi }{q}}x_{n}}\,}

where xn is an integer.

Polyphase sequences are an important class of sequences and play important roles in synchronizing sequence design.
