GSM校准时如何修改GMSK和EPSK的期望功率
[SOLUTION]
GMSK的期望功率在CFG文件中修改WANTED_P(以GSM850举例):
[TX PCL table]
GSM850_CAL_PCL = 17, 12, 5,
GSM850_2CAL_PCL = 19, 5,
GSM850_PCL = 19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,
GSM850_CHECK_PCL = 19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,
GSM850_MAX_P = 6,8,11,12,14,16,18,20,22,24,26,28,30,32,33.5,
GSM850_WANTED_P = 5,7,9.1,11,13,15,17,19,21,23,25,27,29,31,32.2,
GSM850_MIN_P = 4,6,8,10,12,14,16,18,20,22,24,26,28,30,31.2
GSM850_C = 8,10,11,12,13,15,17,19,21,23,27,30,35,40,40,40,
GSM850_CORRECTION = 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
EPSK的期望功率在INI文件中修改8-level PA TX power (以GSM850举例)
[EPSK GSM850 level, ramp]
8-level pa control subband high weight(dB)=0.12500,0.00000,-0.12500,-0.25000,0.00000,0.00000,0.00000,0.00000,0.00000,0.00000,0.00000
8-level pa control subband low weight(dB)=0.12500,0.00000,-0.12500,-0.25000,0.00000,0.00000,0.00000,0.00000,0.00000,0.00000,0.00000
8-level PA TX power level(dB)=5.00000,7.00000,9.00000,11.00000,13.00000,15.00000,17.00000,19.00000,21.00000,23.00000,25.00000,27.00000,27.00000,27.00000,27.00000,27.00000
