My problem is that I cannot create the same sequence (even the 4 first output) with my PN-sequence generator.
I have read the ITU 0.150 standard, but I didn't get the solution.
I tried to implement based on the following schematic from this document.
The time elapse from top to down, and each row shows a snapshot of the shift register. I hoped that the column
I results the PN-sequence.
Cells in the first column has the feedback formula. (Eg.:
=IF(OR(AND(E1, NOT(I1)), AND(NOT(E1), I1)), 1, 0))
All other cells gets its value from the top left cell. (Eg.: The
B2 cell formula is the following
