Summary:
This paper describes a Field Programmable Gate Array (FPGA) based 2x2 MIMO testbed which employs a new semiblind method for channel estimation. The RF part of this system is built using commercially available components and in-house developed antennas while commercially available FPGA hardware is used for fast processing of Intermediate Frequency (IF) signals. The operation of this MIMO testbed is verified at the IF level for an Alamouti transmission scheme using a purpose developed channel emulator.
