Unformatted text preview: CN(0, 1). The additive noise at the receiver side is also modeled as independent complex Gaussian random variables with mean zero and variance one. (a) Simulate a MIMO system with 2 t M = transmit antennas and one receive antenna by using the orthogonal spacetime code 2 1 2 ( , ) G x x , i.e., the Alamouti scheme, in which 1 x and 2 x are chosen from QPSK signals {1, 1, j, j}. (b) Simulate a conventional communication system with single transmit antenna and single receive antenna, also use QPSK signals. Plot simulation results in terms of biterrorrate (BER) vs signaltonoise ratio (SNR). Compare the results from (a) and (b), and explain your observations. (Note: Use ‘semilogy’ to plot the BER curves and convert the SNR in dB.)...
