Abstract(in English) | The blind adaptive interference canceller using the constrained minimun output power algorithm cancels co-channel interferences without any prior information of other user's codes. However, it tends to cancel a desired signal due to non-orthogonality caused by the frequency selective fading. In order to protect a desired signal, high pass filter is used in the previous method which required a large amount of computational complexity. In this paper, we propose a simple adaptive interference canceller. which significantly reduces the computational complexity, yet achieves almost the same BER performance as the previous method. The performance in the system with voice activation is also evaluated through computer simulations. |
