各种移动通信制式频率与信道号之间的换算

1、各种移动通信制式频率与信道号之间的换算一、gsm信道与频率的换算45mhz19mhz6mhz19mhz6mhz移动联通移动联通890mhz909mhz915mhz935mhz960mhz954mhz25mhzgsm多址方式：tdma（时分多址）gsm双工方式：fdd（频分双工）gsm占用带宽：上下行各25mhz（上下行共用以fdd方式工作）gsm上下行频率隔离：45mhzgsm信道间隔：200khz移动占用带宽：上下行各19 mhz 上行：890mhz 909mhz 下行：935mhz 954mhz （1 95）联通用带宽：上下行各6 mhz 上行：909mhz 915mhz 下行：954mh

2、z 960mhz （95 124）gsm一般换算公式：信道频率：上行：890+ch0.2=f上行（mhz）下行：935+ch0.2=f下行（mhz）频率信道：上行：（f上行-890）5= ch下行：（f下行-935）5= chgsm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：频率信道：下行：（f下行-954）5+95= ch上行：（f上行-909）5+95= ch信道频率：下行：（ch - 95）0.2+954=f下行 上行：f下行 45= f上行注：gsm中95频点为保护频点，无委规定联通、移动均不能占用，因此该频

3、点内信号较为干净如做模拟测试可考虑采用该频点。二、cdma信道与频率的换算45mhz10mhz10mhz联通联通825mhz835mhz870mhz880mhz天宇天宇隔离频带824mhz869mhzcdma多址方式：cdma（码分多址）cdma双工方式：fdd（频分双工）cdma占用带宽：上下行各10mhz（上下行共用以fdd方式工作）cdma上下行频率隔离：45mhzcdma信道间隔：1.23 mhzcdma带宽： 上行：825mhz 835mhz 下行：870mhz 880mhz （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

4、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：869 mhz信道间隔：0.03 mhz ( 即30 khz )cdma每载波带宽为1.23 mh即41个amp频点cdma一般换算公式：信道频率：上行：824+ch0.03=f上行（mhz）下行：869+ch0.03=f下行（mhz）频率信道：上行：（f上行-824）0.03= ch下行：（f下行-869）0.

5、03= ch工程算法：cdma基本频点：877.49 mhz - ( 283 )信道间隔：1.23mhz - ( 即41个amp频点 )信道频率：877.49-（283-ch）1.23=f下行 f下行 45 = f上行频率信道：283 （877.49 - f下行）1.23 41= ch 283 （832.49 f上行）1.23 41= ch注：现联通cdma段虽然有10m带宽，但由于cdma为自干扰系统，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。三、dcs信道与频率的换算联通移动1710mhz联通移动10
