DESIGN AND IMPLEMENTATION OF MIMOOFDM RECEIVER SECTION FOR WIRELESS COMMUNICATION

The widespread popularity of mobile phones, wireless communication and Computer networking added an exceptional growth to the telecommunication industry in recent years. This demand is constantly growing which needs the secure, robust and reliable connectivity. This growth is limited due to the limitations of available frequency resources, Bandwidth, channel capacity, complexity, reliability, transmission data rate, physical areas and communication channel between transmitter and receiver of traditional wireless communication system. Multi-Input-Multi-Output (MIMO) is an efficient Future Wireless system to meet the heavy demand of Wireless communication in available limited frequency resources. This paper address a Compatible advance MIMO-OFDM WLAN Receiver system with OFDM framed in WLAN standard to deal with data signals of BPSK/ QPSK/16QAM/64QAM/256QAM constellations with different forward error correcting codes in MIMO communication modes for establishing a robust wireless communication link. The Wireless communication system is designed for Xilinx family FPGA devices and the performance of MIMO is checked over SISO/MISO for compatibility, Data rate, BER, optimized resource utilization and reliability of communication link to handle the traffic of multiuser though multiple channels, to ensure the transmission and reception of quality signals even in the failure of any channel.
