【摘要】 利用直射信道和瑞利衰落信道模型构造莱斯信道模型,给出莱斯衰落情况下MIMO系统各态历经容量计算公式.仿真结果表明,天线间距越大,来波角度扩展越宽,平均达到角越接近阵列垂线方向,相关因数越小,信道各态历经容量越大;反之,相关因数越大,信道各态历经容量越小,且随着衰落因子的增加,系统的信道容量逐渐减小.更多还原

【Abstract】 Rice channel was constructed by using LOS and Rayleigh channel models,the calculation formula of MIMO ergodic capacity was derived in the case of Rice fading,simulation results shows that the larger the antenna interval is,the wider is the extension of the angle of arrival,and the more the average angle of arrival is close to the perpendicular direction of array,the smaller is the correlation coefficient,and the weaker the spatial correlation is,the larger the ergodic capacity of the channel is and vice versa.With the increase of the fading factor,the channel capacity decreases gradually.更多还原
