Performance Analysis of MIMO-OFDM Wireless Communication System using QAM Modulation Scheme

Orthogonal Frequency Division Multiplexing (OFDM) is expected to be enforced in future broadcasting and Wireless native space Network (WLAN) systems due to its strength in transmittal a high knowledge rate. With the speedy growth of digital communication in recent years, the want for high speed knowledge transmission is increased. OFDM could be a promising resolution for achieving high knowledge rates in mobile atmosphere, owing to its resistance to ISI that could be a common downside found in high speed digital communication. A multiple-input multiple-output (MIMO) communication System combined with the orthogonal frequency division multiplexing (OFDM) modulation technique can bring reliable high knowledge rate transmission over broadband wireless channels. This paper presents the style and implementation of MIMO-OFDM transceiver system for high speed Wireless Network Using MATLAB simulation. In this paper we tend to aim to investigate the impact of weakening channel on the performance of the MIMO- OFDM system with totally different code rate and modulation schemes affects the bit-error rates (BER). The performance of MIMO- OFDM is evaluated on the premise of various parameters.
