Performance Evaluation of BER For MIMO OFDM Systems Using MMSE

Wireless communication is characterized as the transfer of the information between two points physically connected and the separation between them may vary from meters to kilo wireless communication is changing its scenario due to its ease of availability and reliability and lower costs and small sizes and also due to continue research. Multiple Input Multiple Output (MIMO) is a smart antenna technology in the current wireless communication systems, such as 3G and 4G. MIMO can be combined with Orthogonal Frequency Division Multiplexing (OFDM) to improve communica and transmission rate. MIMO OFDM system also gives very good Bit Error Rate (BER) performance. Since MIMO uses multiple transmitting and multiple receiving antennas
