OFDM Channel Characteristics and Channel Transmission Simulator
OFDM channel characteristics transmission simulator, which implements MIMO-OFDM channel modeling with configurable parameters including noise variance, antenna configuration, and input symbols. Key inputs: sig2 - noise variance, Mt - number of transmit antennas, Mr - number of receive antennas, x - complex input symbol vector/matrix (for MIMO systems, columns represent antenna outputs per time instance). The simulator implements frequency-selective channel modeling using block-Toeplitz matrix representation.
