| Abstract: |
| Starting with the performances such as error rate, frequency
utilization and throughput,this paper analyses and compares the
suppressing interference methods and related technologies for OFDMA(Orthogonal F
requency Divided Multiple Access) systems, as we
ll as advantages and disadvantages of performance of these technologies in reduc
ing error rate and improving frequency utilization and throughout, etc. Meanwhil
e，it analyses those problems concerning the development of co-channel interfere
nce(CCI) suppression technology in future mobile communication systems,which pro
vides the foundation for further research on CCI suppression technology. |
| Key words: OFDMA co-channel interference interference suppression performance index |
