Reply To: Size of channel matrix H



unfortunately there are different notions of channel matrices used in the simulator. Please note that a random realization of a channel matrix is generated every subframe (TTI) such that checking the channel matrix after a finished simulation is not very representative. However, the most commonly used notion of channel matrix in the simulator is of size: number of subcarriers x number of OFDM symbols x number of receive antennas x number of spatial transmit layers, for example in your case this could be 72x14x4x2 for 1.4 MHz of bandwidth.

Although I am not sure why the channel matrix dimension is of interest for you, I advise you to check the size of one channel matrix representation directly in the code by debugging rather than after the simulation.
