This slide shows the optical ZCZ sequence set and its periodic correlation functions.
An optical ZCZ sequence set is a set of pairs of bi‐phase sequences and binary sequences.
The element of bi‐phase sequences is either 1 or ‐1.
The element of binary sequences is either 1 or 0.
A periodic correlation function between a bi‐phase sequence and a binary sequence is given by this equation.
Then, this sequence set is called an optical ZCZ sequence set.
This figure shows its autocorrelation and cross‐correlation function.
Shift 0 is a peak w of the autocorrelation function.
On the other hand, the cross‐correlation function is 0 at the shift 0.
