Abstract
This paper analyses the Alamouti scheme for different antenna configurations and different modulation types,
namely BPSK, QPSK and QAM. All configurations were modeled and simulated in MATLAB. A MIMO
receiver for a 21 antenna configuration and BPSK modulation was implemented in a FPGA. The FPGA
results indicate that the Alamouti scheme is a good design option for hardware implementation of a MIMO
receiver. The receiver uses only about 10% of the resources of a medium-sized FPGA and achieves almost
300 Msymbols per second.
