摘要 为了寻找多漏缆传输构成的MIMO系统中漏缆间距对信道容量影响小的原因,用S参数建立了理论模型,计算了耦合系数,分析了互耦效应对信道容量的影响。对漏缆构成的2×2MIMO信道进行仿真,并与采用半波偶极子天线作为发射天线的MIMO系统进行对比,发现了漏缆间互耦效应与系统容量密切相关。 In order to find the reason that the spacing of leaky coaxial cable has little influence on the channel capacity in the MIMO system composed of multi-leaky coaxial cable transmission,the theoretical model is established by S-parameter,the coupling coefficient is calculated,and the influence of mutual coupling effect on the channel capacity is analyzed.The 2×2 MIMO channel composed of the leaky coaxial cable is simulated and compared with the MIMO system using the half-wave dipole antenna as the transmitting antenna.It is found that the mutual coupling effect between the cables is closely related to the system capacity.
