| 摘 要： | MIMO(Multiple-Input Multiple-Output)理论试图在Shannon信道容量公式基础上导出正比于收发信天线数的MIMO无线信道容量(wCC)公式.由于MIMO系统同时使用多根天线发送同频信号,在MIMO的物理信道中会包含多个虚拟独立瑞利衰落信道.因此MIMO理论关于独立瑞利衰落信道的定义在实...

| Abstract: | In terms of Shannon formula,multiple-input multiple-output(MIMO) theory tries to derive the formula of wireless channel capacity(WCC),which is proportional to the number of transmitting and receiving antennas in MIMO system.As multi-antenna is used in MIMO system to transmit signals with the same carrier frequency in the same time,one physical channel in MIMO system will contain multi-virtual independent Rayleigh fading channel.So,the definition in MIMO theory for the independent Rayleigh fading channel is ... |
