| Abstract: | To improve wireless channel transmission gain, modulation SNR and reduce modulation BER, the MIMO technology was adopted. The relationship between multiple-input multiple-output antenna number and antenna transmission power and modulation SNR was simulated considering different channel scenarios of LTE-Advanced MIMO. The simulation result proves that the MIMO technology can improve modulation SNR and modulation reliability under different low power channel scenarios of LTE-Advanced MIMO. |
