各种移动通信制式

1、各种移动通信制式频率与信道号之间的换算、GSMGSM信道与频率的换算上下行各25MHzGSM上下行频率隔离：45MHzGSM信道间隔：200KHzGSM一般换算公式:GSM工程算法:低端信道号（即移动较低频率点信道号）的算法：可采用一般换算公式高端信道号（即联通或移动较较高频率点信道号）算法:频率一信道：下行:(F下行-954)X5+95=CH上行:(F上行-909)X5+95=CH移动占用带宽：上下行各19MHz上行:890MHz909MHz下行:935MHz954MHz(195)联通用带宽：上下行各6MHz上行:909MHz915MHz下行:954MHz960MHz(95124)信道-频率

3、离：45MHzCDMA信道间隔：1.23MHzCDMA带宽：上行：825MHz-835MHz下行：870MHz880MHz（37283）现联通所用CDMA-IS95制式为美国高通制定，当时美国为实现AMP（模拟制式）向CDMA的平滑过渡因此定采用双制式兼容方案，即使用同时支持AMP和CDMA的双模手机，并让AMP退出部分频率资源给CDMA使用。因此CDMA信道编号沿用AMP制式的编号方案。（CDMA信道号指与该载波中心频点相对应的AMP信道号，因此CDMA信道频率换算可参考AMP信道编号的算法）AMP起始频点：869MHz信道间隔:0.03MHz（即30KHz）CDMA每载波带宽为1.23MH

4、即41个AMP频点CDMA一般换算公式：信道一频率：上行：824+CHX0.03=F上行（MHz）下行：869+CHX0.03=F下行（MHz）频率一信道：上行：（F上行-824）+0.03=CH下行：（F下行-869）+0.03=CH工程算法：CDMA基本频点：877.49MHz(283)信道间隔：1.23MHz(即41个AMP频点)信道一频率：877.49-(283-CH)X1.23=F下行F下行45=F上行频率一信道：283-(877.49-F下行)+1.23X41=CH283-(832.49F上行)+1.23X41=CH注：现联通CDMA段虽然有10M带宽，但由于CDMA为自干扰系统，

5、因此在CDMA频带前后均留有一段隔离频带，因此现CDMA网络只有7个工作频点，即283、242、201、160、119、78、37。DCS占用带宽：上下行各20MHz(上下行共用以FDD方式工作)DCS上下行频率隔离：95MHzDCS信道间隔：200KHzDCS带宽：移动：上行：1710MHz1720MHz(512561)下行：1805MHz1815MHz联通：上行：1745MHz1755MHz(687736)下行：1840MHz1850MHzDCS一般换算公式：信道一频率：下行：1805+(CH-511)X0.2=F下行(MHz)上行：1710+(CH-511)X0.2=F上行(MHz)频率
