Re: Re: Re: [bluetooth] FH Selector implementaion query...
Hi Khatib,
I've already simulated the FH Selection block and i got the result exactly same as the Sample data.
I have sent you all the files,there are in your mail.
My question is: How to implement for the Data Descrambler design??Please give me some guide.Because I have done the Scrambler design,and got the correct results.
Best regards
Chuan Chew

Hi,
First of all please do not send files over the mailing list send them to my
email directly and after reviewing them we will put them on the CVS.
Second please send me the files of all other blocks.
I'll review the files and send you my comments soon. Did you made a
simulation for them?
>One last question: Can you tell me how is the design for Data
de-scrambler??
What do you mean?
Regards,
Jamil Khatib

uap, and then initialize it as in CASE 1, ie 47 (0100 0111) this will make

you try and then please tell me if it works.
