Description

technical field

[0001] The invention relates to the field of mobile communication, in particular to a multi-mode radio frequency signal generator and a signal generating method thereof. Background technique

[0002] Throughout the current mobile communication market, the coexistence of various systems and the continuous emergence of new systems are the outstanding features of today's mobile communication market. In the digital cellular system, the system with TDMA as the multiple access method and the system with CDMA as the multiple access method coexist, such as the coexistence of GSM, CDMA, WCDMA, etc. From the perspective of global regions, the digital cellular mobile communication system coexists in different regions Different systems, such as ADC in North America, GSM in Europe and China, and JDC in Japan, coexist. Nowadays, new communication systems and standards are constantly proposed, and the life span of communication products is shortened sharply. Therefore, in ...
