2. Assume that you need to design a MIMO system that achieves a diversity order of N:N, using an Nexp orthogonal space-time block code and that that the modulation is BPSK. If there are 5 transmit antennas, what is the minimum length of the code matrix (i.e., minimum value of p) that is needed if a real, non- square OSTBC is used? HINT: All OSTBCs achieve full diversity. 2.
