摘要 采用多输入多输出(multiple input multiple output,MIMO)技术来提高无线信道的传输增益,从而提高调制系统中的信噪比、降低调制系统的比特误码率;仿真量化分析了在LTE-Advanced MIMO不同无线场景中,调制系统中信噪比与MIMO技术的天线数,以及调制系统中信噪比与MIMO技术天线的发射功率之间的关系。仿真结果表明,MIMO技术能提高低功率无线场景中调制系统中的信噪比,进而提高调制系统的可靠性。 To improve wireless channel transmission gain, modulation SNR and reduce modulation BER, the MIMO tech-nology 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-Advanccd MIMO.
