The demand of users increases day by day in context of wireless communication. The current research emphasizes on many factors such as data rate, type of modulation, and characteristics of the channel. Out of all the factors, channel estimation is the interest in this work. In this paper, the channel estimation based on MIMO-OFDM has been performed. The Multiple-Input Multiple-Output (MIMO) system is developed using multiple antennas, where the Space Time Block Coding (STBC), has been tested over Rayleigh's flat fading channel. The concept for wireless communication using MIMO-OFDM has been considered and tested step-by-step. The noise analysis, Bit Error Rate (BER), Symbol Error Rate (SER) has been evaluated.
