| Abstract: | The BER(Bot Error Rate)performance is evaluated of the MC-CDMA system employing such equalization techniques as phase Equalization(PE),Maximum Ratio Combining(MRC) or Controlled Equalization(CE) within its downlink as the frequeney-selecive channel.Numerical calculation and computer scmidation results are given correspordingly.It has been shown that the controlled Equalization with an optimum threshold outperforms other equalization techniques in terms of system BER performance and spectrum officieneg. |
| Keywords: | Multiple channel code division multiple access Channel Equalization |
