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
