    walsh codes in cdma technique

    ok..i didn't know it.. will type properly from now on... once the walsh code sequence or the pn sequence is generated how do we encode the data bits..?? if the data is 101 and say the sequence is 11001100 , are we multiplying it..?? if yes how can i implement it using vhdl..?? should i just code...
