摘要

在移动通信中，宽带传输的接收信号电平不同于窄带传输的接收信号电平。只有少数的研究已经做了澄清接收信号的水平特性的宽带传输。为了使信号级分布归一化，我们提出了一个新的传播参数，称为等效接收带宽2/spl Delta/f/spl Delta/L/sub max/，它是接收带宽2/spl Delta/f与传播路径长度最大差/spl Delta/L/sub max/的乘积。通过计算机仿真分析了这一新的传播参数与衰落深度之间的关系，发现它们密切相关。此外，我们从理论上和计算机模拟的角度研究了接收信号级自相关依赖于接收带宽和路径长度的差异。结果表明，自相关性与两者无关。

Received signal-level, characteristics of wide-band transmission in mobile communications

In mobile communications, the received signal level of a wide-band transmission differs from that of a narrow-band transmission. Only a few studies have been done to clarify the received signal-level characteristics of a wide-band transmission. In order to normalize the signal-level distribution we propose a new propagation parameter called the equivalent received bandwidth 2/spl Delta/f/spl Delta/L/sub max/ which is a product of the received bandwidth 2/spl Delta/f and the maximum difference in the propagation path length /spl Delta/L/sub max/. We evaluated the relation between this new propagation parameter and the fading depth by computer simulation, and we found they are closely related. Further, we have examined the received signal-level autocorrelation dependence on the received bandwidth and difference in path length, theoretically and by computer simulation. The result showed that the autocorrelation was independent of both.
