This model is just testing an idea of MIMO, which IEEE802.11n will have. But I havo not seen the standard, I tried to make it with 11a. Actually this model would not work in real world, because the preambles were not designed to solve the MIMO feature. But this model may be useful to get some idea to start to design a PHY with MIMO. -This model is just an idea of testing MIMO. IEEE802.11n which will have. But I havo not seen the standard.
