| Abstract: | After investigating the performance of JD CDMA/TDMA(joint detection CDMA/TDMA)systems,a modified JD algorithm based on blind channel estimation is proposed.The improved algorithm is superior in that it remarkably enhances the system efficient bit rate and has a better error performance.The performance differentiation between the modified and the original algorithm is analysed and the corresponding computer simulation results are given. |
