Abstract
An Orthogonal Frequency Division Multiplexing(OFDM) has becoming a desirable modulation technique scheme for wireless systems. In recent years, with the advent of technology in Very Large-Scale Integration (VLSI), the number of higher data level is growing. Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems are used to meet these criteria due to their high performance, in terms of transmission range, data rate resistance to multi-path transmission. A MIMO OFDM framework is designed for systems such as IEEE 802.11n, 4 G and LTE in advanced communication systems. It provides secure transmission with a growing coverage area. The estimation of Channel State Information (CSI) is the biggest challenge in the implementation of MIMO-OFDM method. We evaluate and enforce the pilot-based channel analysis methods for MIMO-OFDM system such as Minimum Mean Square Errors (MMSE), Least Square (LS).
