Effect of Scattering Parameters On MIMO System Capacity

Abstract

In this paper, the influence of scattering parameters on MIMO system capacity are discussed by de- signing MIMO antennas. In principle, the capacity of MIMO system can be increased by installing a high num- ber of antennas both at the transmitter and receiver. However, scattering parameters also play a vital role in the capacity of MIMO system. This behavior of capacity is observed in case of partially and fully correlated environment in the presence of scattering parameters. MIMO to explain in detail the effect of scattering parameters on the capacity of MIMO in correlated environment. We focused our analysis of capacity for partially and fully correlation situation. The capacity of MIMO based antenna systems givesa reasonable increase in capacity by installing a high number of antennas at the transmitter and receiver side. However, this method introduces not only signal correlation (7), but envelope correlation as well (8). Reflection and transmission coefficient of scat- tering parameters are attained by designing microstrip patch antenna. The desired results to analyze the antenna performance are acquired by using a probe feed mechanism in patch antenna design. The plots of MIMO for two transmit and receive antenna are examined. We exploited scattering matrix with the help of scattering parameters of reflection and transmission using suggested design. Consequently, the effects of partially and fully correlated MIMO system on capacity by using scattering matrix are stud- ied.Comparative analysis of the percentage decrease of capacity in the presence of scattering matrix is also ob- served in Figure 5. The value against these Plots are shown in Table I. A detailed analysis proposed antenna and the expression of capacity in term of scattering parameters is presented in the next sections.
