Theoretical Design of Mimo Transceiver and Implementation Its Transmitter Using Fpga

Abstract

The use of multiple transmit and receive antennas (MIMO system) is widely accepted in recent years, as a promising technology for future wireless communication, to achieve higher data rates independently of transmission power and bandwidth, with improve system reliability through increasing diversity. This research presents the design and implementation of a multiple antenna wireless communications system using Xilinx Field Programmable Gate Array (FPGA) .The proposed design based on Alamouti’s transmit diversity scheme which is a space-time block code (STBC) with two transmit antennas and an arbitrary number of receive antennas. The implementation demonstrates the space-time code in a baseband system with two antennas for transmitter and receiver. The encoding and decoding algorithms are implemented using VHDL, Spartan 3A /3AN is used to implement transmitter part, where the Virtex2P is used to complete the receiver part design theoretically. Finally the design MIMO systems are implemented successfully.
