12 Aug 2007	Muhammad Rizwan	Hi, I want to know something if you can help. I have spread the bits with walsh code then with PN code and added awgn noise to it. On receiving side when I multiplied this received signal with conjugate of PN code it was removed from bit .Now how can I remove the walsh function to gain actual original bits.
