16.0 Let's test our knowledge of Correlation by participating in a Correlation Workshop.
Correlation Workshop
Let C2 (t) = 1 0 0 1 0 1 1, be the Sequence or Code generated by a 3-stage Linear Shift Register:
- Comment on the code Length and its Balance property
- Compute the various time-shifted versions C2 (t)
- Compute and plot the Autocorrelation function of C2 (t)
- Draw some conclusions about PN Codes and their autocorrelation properties
Let C1 (t) be: 0 1 1 1 0 0 1 and Let C2 (t) be: 1 1 0 1 0 0 1
- Compute the various time-shifted versions C2 (t-
i ) of C2 (t)
- Compute and plot the Cross-correlation function [C1 (t) · C2 (t- i )]
- Compare with cross-correlation C2 (t) · C1 (t- i )
Generate your own maximum-length PN codes using a 4-stage Linear Shift Register and repeat above exercises
