| 摘 要： | 在得到Rician衰落下正交空时分组码接收信噪比的基础上,首先得到了单位时间片上Rician衰落下正交空时分组编码信道的平均容量,并通过Porteous引理进一步给出了一种衰落环境下平均信道容量的近似计算方法.通过与数值积分以及Monte Carlo仿真结果的比较表明:文中给出的表达式完全可以用来近似计算Rician衰落下的平均信道容量,且非常容易.

| Abstract: | On the basis of analyzing the received signal-to-noise ratio of orthogonal space-time block codes over Rician fading channel, the average capacity over Rician fading environment for orthogonal space-time block codes is obtained in this paper. Then the simple but accurate formula for average capacity is further deduced by Porteous's lemma. In comparison to the Monte Carlo and numerical integral, the simulation results show that the approximate value obtained by the formula in this paper is very accurate while it shows much lower complexity. |
