2x2 MIMO-OFDM system

The task is to design a working Xilinx DSP system generator(sysgen) design, sysgen is a module of blocks integrated to simulink in order to automatically generate a vhdl code and bit stream to be uploaded in a FPGA board without conversion. The design should be of a 2x2 Multiple input Multiple Output system using OFDM( Orthogonal Frequency Division Multiplexing), using any encoding technique (BPSK,QPSK,QAM) with Alamouti's Tx. Technique in the transmitting side and any detection technique on the receiving side. Here are few papers that will help you understand more what it is trying to be done,
