| Abstract | ||
| In all the CDMA systems (all types of CDMA systems), the signal to be transmittedthrough the channel is real valued signal. In this research the signal is complex and can besent on I – Q carrier of the same frequency, it is possible to send the real valued signal by thesame method mentioned above but it must be normalized before sending it. In this method itdoesn’t need to be normalized. The bit error rate as compared to the conventional method wasvery good. The program was written in Matlab 2009b | ||
