Design of DFE Based MIMO Communication System for Mobile Moving With High Velocity
Reliability, high quality, and efficient data rate communication for high speed mobile is the growing research in recent years. In this paper, time dispersive and frequency dispersive effects on signal is analyzed. Then a decision feedback equalizer is proposed whose weights are periodically updated using LMS algorithm depending upon the statistical parameters of fading channel. In order to combat the effect of fading a MIMO wireless communication technique is used. Finally, the performance of the system under high time dispersive and frequency dispersive channel is analyzed while the velocity of the mobile is taken as high as 250km/hr.
