Hi friends
I am designing DSS (direct spread spectrum system).at this moment I have been designing a transmitter unit .I have a data signal with the frequency of 1 KHz and I have a PN code generator which has a frequency of 1MBPS ans i am EX-ORing (BPSK modultion) this 2 signals and now i want to transmit the modulated wave and i want to recieve the signal at receiver side .

My experiment is limied to the lab environment.


Any body could please let me know how can i achieve this ?how should i proceed for Antenna design for the above system.?
I am new to this stuff coud any one please give some insight of the issue?

Thanks a lot
Harsh

Hi Harsh. There is one very important question that needs to be asked... I hope everyone will bear with me before getting to it.

I am curious to know, first... what is the function of the product you are trying to build, whom are you building it for, and what is your professional background?

Yeah, it kind of seems like BS to me.

If you are really a student in New York, I recommend going to the college library and looking at some books. You need to develop your skills a bit more... you have asked a question that has a complex answer not really fit for a quick bulletin board answer.

If you aren't a student in New York, well I recommend you taking a good hard look at the world with an open mind.

Hi ,
This was the last best thing i wud like to hv on earth .If u cant reply then dont suggest such a thing,I hv tried diiging in to books and as far as i know the bulletins are for quick and better support so that novice can quickly get in to the technical domain and can explore and deliver nore to the world.

Sorry for the reply but i am being frank to you..


Thanks
Harsh

Are you guys pulling my leg, or is the thing/device/contraption/implement/doohickey being referred to here really some sort of doomsday machine?

It appears to be quite fearsome whatever it is.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
