| Abstract: | In this paper is investigated the issue of equalization for linear SISO time selective fading channel.The SISO system is modeled on a base expansion model and then transformed by over sampling technique and multiaerial reception into a single input multi output(SIMO)system,and the channel is equalized by a special zero forcing equalization.Theoretical research and experimentation have both showed that the proposed scheme is simpler in calculation,better in performance,and quicker in equalizing the channel in comparison with some conventional schemes. |
