Analysis on the RF interference in GSM/CDMA 1X dual-mode terminals
This paper is to study on the RF design of GSM/CDMA 1X simultaneous dual-mode mobile terminal. First, considering government regulatory requirements, the main RF interference between GSM and CDMA 1X units in the terminal and the required C/N at CDMA unit input for the receiver normal operation is analyzed. Secondly, the C/N at CDMA receiver input under the cases of Co-channel and adjacent channel interference generated by GSM transmission are calculated respectively. Finally, the solution for suppressing the interference of GSM transmission to CDMA in a GSM/CDMA 1X dual-mode terminal design is given and experiment results are shown. With several methods adopted in the real product design, the GSM/CDMA 1X simultaneous dual-mode mobile terminal was successfully developed.
