| Abstract | ||||
| ABSTRACT This problem of the co-channel interference arises extensively in the cellular channels, which degrades significantly the performance of the cellular system. The interference signals are indeed the transmitted signals of the adjacent user in the neighboring zones. Then, the cancellation of these interference signals is of great interest to improve the system performance. However, the signal of interest is not known in advance. Hence, the classical method of noise cancellation is inefficient. The adaptive interference canceller (AIC) is introduced to cancel the co-channel interference signals. A distributed AIC is proposed to cancel six interference signals. The proposed AIC has succeeded to cancel six interference sources and it exhibits a great improvement in the output signal to interference ratio. | ||||
