Implementation of the independent component analysis processing circuit for wireless communications by FPGA

The blind estimation technique is very useful for an adaptive antenna and a MIMO communication system. Independent component analysis (ICA) which is studied briskly in the field of image processing or signal processing, is convenient means because there are few restrictions of previous knowledge. In order to perform signal separation by ICA on real time, it is necessary to perform repeated calculation of restoration vectors to less than about 0.4 millisecond. In this research, FPGA implements a part of processing of the complex value fastICA which is a way method of ICA. Main results show that the FPGA´s computation is about 1000 time faster from PC´s computation. Thereby, realization of a real-time operation will also be considered from now on.
