| Abstract(in English) | The blind signal processing is useful for radio communication technologies such as an adaptive array antenna and the MIMO communication system which effectively utilize frequency resources. The independent component analysis (ICA) developing in the area of the image processing and the speech processing is a simple algorithm with demand upon less prori knowledge. In this report, it is described that the blind signal separation of the mixture signal consisted of multipath-faded signals with QPSK modulation using fastICA Algorithm for complex-valued signals. The simulations were carried out in the model that describes such situation that mixture signal consisted of direct waves and interference waves with uniform intensity from 4 signal sources is received at 4 elements Array Antenna. It is demonstrated that ICA can be applied to the blind signal separation in multipath fading environment. |
