    hello,

    I'm designing in VHDL a digital matched filter for DSSS
    transmission....

    The problem is that there's a lot of undesirable pulses beetween the
    autocorrelation pulses...

    I uses Barker and m sequences...

    Is there anyone who have already designed this kind of filter ?

    Thanks

    How about rest of stream, is it scrambled?

    Try another Barker's code word.
