To Study the Multipath Effects incorporating User Motion and it's Retaliation in MIMO Technique

In telecommunication and networking, wireless mobile communication technology has emerged as the most exciting area of research. The tremendous growth of various satellite services, cellular mobile use and the wireless Internet are creating rapid changes in computer networking and telecommunications. It is clear that number of mobile users is increasing very rapidly. However, as more users try to access simultaneously, the interference level and hence the error rate increases; only gradually does the system degrade to the point of an unacceptable error rate. Hence, in the present work we have employed the MIMO technique to avoid such degradation. At the beginning we have calculated the free space loss matrix (α) for distance matrix (d) with in 1 Km. Then we have calculated the Weight matrix (X) and finally we have calculated the output of the desire signal (Y)[6][11]. At the same time we have studied the variation of carrier to interference signal strength ratio with the number of users. The performance of the proposed system is also compared with the existing one. The result shows a significant improvement over the existing system performance. In the present study we have kept the number of antenna fixed but number of users is varied to study the effect.[1][9][11] General Terms Wireless Mobile Communication, MIMO, Multipath Effects, CDMA
