Hi, I am trying to use the GLFSR source in GRC with PN correlator for system identification. What I want is to generate a sequence from the GLFSR source and to get an estimate when the PN correlator uses the same sequence and to get zero when the sequences generated by the GLFSR and the PN correlator are totally orthogonal for any delay.
To make this, I need to know how to generate two orthogonal PN sequences from two different GLFSR blocks. I tried to use different seed parameters, but I saw that the two sequences are still correlated for some delay (shift). Anyone who has done this before ? In short, how can I generate two PN sequences which are orthogonal for any delay ? brex
