Abstract: This paper address the Design and implementation of Alamouti Transmit Diversity Scheme using FPGA for Multi-Input-Multi-Output (MIMO) wireless communication transmitter. The task of the FPGA based MIMO Encoder is to process two digital signals (S1 & S1) having real(q) and Imaginary (i) parts, are being transmitted using two transmitting antennas by employing Alamouti transmitting scheme in VHDL. The FPGA devices of the Xilinx family are used to report the results. The performance is checked for optimized device resource utilization, data link for two symbol period. The role of MIMO Encoder/transmitter to handle the traffic of multiuser though multiple channels, to ensure the quality signals at the receiver even in failure of any channel.
