PN Sequences By Dr. Ernest Simo 6.0 Correlation Workshop 1 - Let code C2(t), generated by a 3-stage LSR, be: 1 1 0 1 0 0 1  Comment on the code length and its Balance property Compute the various time-shifted version C2(t) Compute and plot the Auto-correlation function of C2(t) Draw some conclusions about PN Codes and their Auto-correlation properties. 2 - Let C1(t) be: 0 1 1 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) 3 - Generate your own maximum-length PN Code using a 4-stage Linear Shift Register and repeat above exercises.
