hello, I have research on the implementation of MIMO-OFDM alamouti on USRP N-2920 using labview. In the meantime, I've been working on an OFDM MIMO transmitter with alamouti. but I'm having a hard time working on the receiver. One of the things that I find difficult is about channel equalization. This happens because the estimated channel has the same number of signals received at the receiver. Thus each time slot is influenced by the channel. However, if I look at some examples of the application of the Alamouti algorithm, the channel coefficient is usually 1 for each channel, such as h1, h2. does anyone have a solution for this problem? Thank you
