Summary:
The blind estimation technique is useful for an adaptive antenna, and a MIMO communication system. These wireless technologies perform feedback control that the optimal system performance is obtained by adjusting a system parameter according to the radio wave situation observed with a certain means. In this system parameter determining method, Independent component analysis (ICA) is very useful. ICA is the blind estimation technology which developed remarkably in recent years. Based on the statistical independency of a signal, it is the method of finding out a desired signal out of the crowded noise. The method has developed focusing on the field of image processing or speech signal processing. The application to various fields is progressing by the appearance of the robust and high-speed algorithm fastICA by Hyvarinen. Since calculation of ICA is iteration of matrix calculation. Matrix calculation is suitable for FPGA.
