Hi, I use ADS2005A. I want to simulate the wimax802.16e DL with 2-Tx antennas and 1-RX antenna. In this case the Alamouti code will be used as a transmission code. But my problem is in receiver side, after adding two paths h11 and h21 from two Tx at receiver. I can not find any parameters at the receiver block to indicate the MIMO case. Because at receiver block channel coefficients for two paths should estimate for detection and I do not know how it will be down if I do not declare to the receiver that I have two antennas at transmitter side not one antenna.
