Abstract

This paper reports on the development of a semi-blind channel estimation algorithm that is aimed for inclusion in a 2times2 multiple input multiple output (MIMO) system. The system employs a field programmable gate array (FPGA) for fast processing of transmitted data. Its RF part is built using commercially available components and in-house developed antennas. FPGA hardware is used for fast processing of IF signals. The performance of the developed channel estimation algorithm is tested assuming the Alamouti coding scheme. An in-house developed MIMO channel emulation algorithm is applied during these tests.
