| Abstract | ||
| Code Division Multiple Access (CDMA) transceiver is used for transmitting and receiving multiple digital signals simultaneously over the same carrier frequency (the same channel). Although used in various radio communications systems, the most widely known application of CDMA is for cell phones. This paper refers to channel estimation based on time-domain channel statistics by using a general model for Stanford University Interim (SUI) Channel Models. the aim of the paper is to find out the most suitable channel estimation algorithms of the CDMA baseband transceiver based on multiwavelet signals and modify the bit error rate for this system starting with the analysis of channel estimation algorithms. we present the Minimum Mean Square Error (MMSE (and Least Square (LS (. A comparison has been condncted between performances under different SUI channel scenarios. The bit error rate for a 16-QAM and OFDM system based multiwavelet signals is presented by methods of Matlab simulation results. | ||
