pseudo random sequence

hi,

i have to generate a 64 bit length pseudorandom sequence. I mean to code in VHDL. Is there a necessity for knowing the polynomials that are required for genereating the sequence... or how to know from which of the register i have to tap the output??? i wanted to know this method for generating any length PN sequence. or any other way out is there? pls help me...

regards,
arunmit168.
 

Re: pseudo random sequence

there are some books which have existing circuits.
so you can use it directly.
one book named "scrambling and discrambling", maybe it is.
i am not sure. i ever read it.
this book is wrote by two Koreans.
 

Re: pseudo random sequence

This is the matlab source code to generate pseudo sequence.

pseudo random sequence

Hello Everyone. I need to generate a binary data stream of duration Ts. After, I need to collect the even bits to create the in phase stream and stretch these slot in duration 2Ts.

I need to do the same for the odd bits.

Can you please help me
