What is the relation between the number of senders and walsh code in CDMA code ?

[shuoqin]

I am doing a project about CDMA. and i meet some problems which are as follows: what is the specific relation between the number of senders and the number of walsh code? I know the ideal situation is that these two numbers should be the same. However, I heard the fact that the number of code should be less than the number of senders which send the data at the same time. I need to know this kind of relationship. Is there a forum? Thanks a lot~

The no. of "senders" (users) is equal to the length of the Walsh code

Its not the ideal one, this is what you need to have for simultaneous transmission.

Is there a forum? Thanks a lot~

well THIS is a forum, so the answer is Yes

Thanks a lot~
