七、对快衰落的防护度对快衰落的防护度究竟多大,将取决于对通信可靠性的要求、采用分集的重数和合并方式。下面仍以最大比值合并方式为例来说明如何利用已推导出的可靠性曲线来计算防护度M_R。图14为理想分集条件下,采用最大比值合并方式的通信可靠性曲线。参数为分集重数,横座标为防护度 M_R,纵
Seven, the rapid decline of the degree of protection against the rapid decline of the degree of protection will depend on the reliability of the communication requirements, the use of diversity and merger weight. The following is still the maximum ratio of the merger as an example to illustrate how to use the reliability curve has been derived to calculate the degree of protection M_R. Figure 14 shows the communication reliability curve using the maximum ratio combining method under ideal diversity conditions. Parameters for the diversity of heavy, horizontal coordinates for the degree of protection M_R, vertical
