    pn sequence generator

    I am trying to do pn sequence generator to remove the spur for phase dithering in Matlab simulink.

    I can generate the specific system noise level by using pn sequence simulink model. But this does not reduce the spur due to phase dithering and this system noise level is quite high.

    Q1) how to adjust the parameter of pn sequence generator simulink model to reduce the system noise level?

    Q2) why this does not reduce the spur level?

    Q3) Is the max length tap sequence used in pn sequence simulink model same as that of LFSR such as xilinx LFSR application note?

    circuit diagram of pn sequence generator

    You can generate PN sequence by using shift registers, see the diagram:



    where h can be either 1 (short circuit) or 0 (open circuit)
    and x's are the shift registers...


    if helps, press helped me

    pn sequence generator circuit

    the code of a pn sequence is simply apolynomial,

    see this table:


    so the code is very simple...
