频点与频率:
联通WCDMA上下行各15M带宽,WCDMA单载波宽度为5MHZ,那么应该就有3个频点吧,请问这三个频点中心频率是怎么计算的,
联通频段:1940MHz-1955MHz(上行)、2130MHz -2145MHz(下行)
计算绝对频点号使用200k一个栅格,那么1兆就是5个单位栅格了,就是乘以5
下行频点10713(中心频率2142.6MHz)、10688、10663,频点/5=中心频率。每个频点间隔25,25×200K=5M。
上行频点9763(中心频率1952.6MHz)、9738以及9713。
W带宽为5mhz,中心频点为所用频率除以5,比如
下行10713/5=2142.6MHz
上行9763/5=1952.6MHz,
另有
二载波9738/10688
三载波9713/10663
频点号=中心频率*5就对了,中心频率就是那5M带宽的中值,比如中心频率2142.6对应的频点是10713
