Description

The MIMO-OFDM system mainly used to the wireless communication based applications. The MIMO process focused by the multiple input and multiple output section. The communication process is to optimize the energy consumption level on the original transmission input signal level. And the signal process is to effectively improve the wireless communication applications. This technology to be modified using the HARDWARE based VLSI architecture. This architecture is to improve the transceiver performance in 802.11 MIMO-OFDM systems. This system to design the 4*4 MIMO-OFDM architecture in Matlab-simulink software combined with hardware FPGA board. The Matlab simulation is to convert the VHDL code and to check the output for VLSI simulation graph. To design the blocks in simulink unit. And to modify the block arrangement in overall OFDM-MIMO unit and to develop the sub system functions also. And the process is to optimize the transmission timing about MIMO architecture process. The system generator and Xilinx software to implement the hardware architecture about simulink 802.11 MIMO-OFDM system design. The design methodology to optimize the hardware program design process based upon VHDL code for MIMO encode and decode process and the transceiver functions. The simulink is to arrange the MIMO-OFDM various blocks and improve the energy efficiency in wireless communication system.
