| Abstract: |
| Using the structure of Serial Interference Counteract(SIC) multi-user detection(MUD) and combining the space-time RAKE receiver,a new SIC MUD algorithm is proposed.The results of simulation indicate that this algorithm can improve about 5dB gain than the traditional space-time RAKE receiver and the error rate is greatly improved. |
