Short description: Sequence whose terms are complex roots of unity
In mathematics, a polyphase sequence is a sequence whose terms are complex roots of unity:
- [math]\displaystyle{ a_n = e^{i\frac{2\pi}{q}x_n} \, }[/math]
where xn is an integer.
Polyphase sequences are an important class of sequences and play important roles in synchronizing sequence design.
